1 2007-02-08 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi (Parentheses): Mention problem with (( in
4 shells.
6 2007-02-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7 and Paul Eggert <eggert@cs.ucla.edu>
9 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix quoting
10 errors introduced in last change.
12 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
14 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Prefer \r to
15 an actual carriage return. Use "ac_cr" to contain the actual
16 carriage return.
17 * doc/autoconf.texi (Limitations of Usual Tools): Document problem
18 with traditional Awk and begin.
19 * tests/torture.at (Limitations of Builtins): Document the problem
20 with Bash 2.03 printf.
21 (Substitute and define special characters):
22 Remove trailing white space. Work around a bug in Solaris 8 /bin/bash.
24 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
26 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
27 input from /dev/null in awk test, so even Solaris /usr/bin/awk
28 will not wait for input with a script containing only a BEGIN
29 rule.
31 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
33 * doc/autoconf.texi (Introduction, Why GNU M4): Clarify M4 version
34 requirements.
35 * README: Likewise.
37 2007-02-02 Eric Blake <ebb9@byu.net>
39 * NEWS: Update copyright.
41 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as
42 broken.
43 * configure.ac: Update error message.
44 * NEWS: Note that M4 1.4.5 or later is now a hard dependency.
45 Reported by Gary Vaughan and Jim Meyering, and problem analyzed

49 2007-01-31 Eric Blake <ebb9@byu.net>
51 * THANKS (people): Update.
53 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
55 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
56 latest version.
57 (Shell Substitutions): Note problems with @{var:=value} etc.
58 Add a new section for problems with @{#var} etc. Problem noted
59 by Ralf Wildenhues. See:
60 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
62 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
64 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
65 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
66 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
67 substitution will still be done by the special code.
68 Report by Jim Meyering.
70 * doc/autoconf.texi (File System Conventions): Mention that
71 $PATH_SEPARATOR is for the build system only.
72 Report by Keith Marshall.
74 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
76 * doc/autoconf.texi (Setting Output Variables): Mention that
77 all non-NUL characters are ok in substituted values.
78 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
79 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
80 carriage return for $AWK, needed for BSD awk.
81 * tests/torture.at (Substitute and define special characters):
82 Test all 8 bit non-NUL characters.
83 Report against Automake by Patrick Welche.
85 2007-01-15 Stepan Kasal <kasal@ucw.cz>
87 * doc/autoconf.texi (Specifying Names): `--host' does not
88 change the build type.
90 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
92 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
93 early on the reader side, drop stderr of the input to avoid
94 `broken pipe' error output; this may happen even with shell
95 builtin `echo' of some bash versions. Reports by Ian Macdonald
96 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
98 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
100 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
101 separate items of `ac_user_opts', to avoid long lines.
102 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
104 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
106 * doc/autoconf.texi: Fix some typos.
108 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
110 Fix some wording problems noted by Paolo Bonzini in:
111 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
112 * doc/autoconf.texi (Signed Overflow Examples): Give more
113 discussion about the allow_superuser_privileges example,
114 and change it a bit to make things clearer.
115 (Optimization and Wraparound): Clarify whether the compiler
116 will generate an infinite loop for the example derived from
117 Autoconf's mktime test.
118 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
119 Also, clarify unsigned multiplication overflow.
121 2007-01-04 Eric Blake <ebb9@byu.net>
123 * bin/Makefile.am (RELEASE_YEAR): New macro.
124 (edit): Use it to supply correct copyright year to scripts.
125 * bin/autoconf.as (version): Use it.
126 * bin/autoheader.in ($version): Likewise.
127 * bin/autom4te.in ($version): Likewise.
128 * bin/autoreconf.in ($version): Likewise.
129 * bin/autoscan.in ($version): Likewise.
130 * bin/autoupdate.in ($version): Likewise.
131 * bin/ifnames.in ($version): Likewise.
133 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
135 * doc/autoconf.texi (Integer Overflow): Revised based on today's
136 feedback. The most important changes document what happens when
137 you convert an out-of-range value to a signed integer type, and
138 say that (sum < a) != (b < 0) reliably detects overflow when sum =
139 a + b.
141 * doc/autoconf.texi (Integer Overflow): Greatly expand and
142 rewrite, taking notions from the recent discussion on the gcc and
143 autoconf mailing lists; please see
144 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
145 and follow the many links.
146 (Integer Overflow Basics, Signed Overflow Examples):
147 (Optimization and Wraparound, Signed Overflow Advice):
148 (Signed Integer Division): New sections.
150 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
152 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
153 preprocessor macro arguments in traced name.
154 * doc/autoconf.texi (Defining symbols): Document longstanding
155 support for AC_DEFINE-ing macros with arguments, and document
156 behavior when the same variable has multiple AC_DEFINEs.
157 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
158 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
159 macros directly, giving much shorter and simpler code.
161 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
163 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
164 space before "$ac_configure_args" to prevent a 'config.status
165 --recheck' failure if ac_configure_args doesn't contain a leading
166 space. This works around a problem with the XEmacs configure.ac,
167 which uses the (undocumented) ac_configure_args variable
168 inconsistently with Autoconf.
170 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
172 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
173 Include <limits.h>, and use its INT_MAX to rewrite the
174 j loop so that it does not overflow 'int'. Problem reported by
175 Ralf Wildenhues in
176 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
177 Play it safe by shifting left by 1 rather than multiplying by 2,
178 as GCC is less likely to optimize this away when the value
179 is signed (when it assumes overflow leads to undefined behavior).
180 Also, don't assume time_t uses two's complement.
182 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
184 * tests/torture.at (Substitute a 2000-byte string): Avoid using
185 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
186 dumps core on it. Report by Tim Rice.
188 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
190 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
191 --disable-option-checking to --help output even when
192 AC_PRESERVE_HELP_ORDER is not used.
193 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
194 --with argument, rather than argument with [-.] replaced by
195 underscores.
196 * NEWS: Fix typo in previous change; the news was in the
197 wrong section.
199 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
201 * NEWS: Warnings are now generated by default for unknown
202 --enable-* and --with-* options.
203 * doc/autoconf.texi (Option Checking): Renamed from
204 (Configure Option Checking). Tighten up the wording a bit.
205 (External Software, Package Options): Cross-reference to Option
206 Checking, and use this to shorten our section.
207 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
208 "$x" to test "x$foo" != x.
209 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
210 Don't warn if $enable_option_checking is "no".
211 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
212 ac_unrecognized_opts to the empty string.
213 Don't echo the unrecognized opts, as this might mishandle
214 backslashes or leading -.
215 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
216 usage next to the other --disable-FEATURE options in the
217 help string.
219 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
221 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
222 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
223 Print warning for unrecognized --with and --enable options
224 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
225 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
226 Disable option checking when subdirs are configured.
227 (AC_OUTPUT): If warnings are enabled, print warning about
228 unrecognized --with and --enable options at the end of
229 the configure output (as well as at the beginning).
230 * doc/autoconf.texi (Option Checking): New node.
231 Document new option warning functionality.
233 2006-12-16 Eric Blake <ebb9@byu.net>
235 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
236 * NEWS: Start news for current version.
238 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
240 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
241 Define HAVE_GETMNTENT to 1, not to the empty string.
242 Problem originally reported by Jochen Friedrich in
243 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
245 This change prompted by a problem report by Andrey Simonenko in
246 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
247 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
248 object-like macros only, in the traditional portable character
249 set.
250 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
251 Warn about attempts to define things that are not identifiers.
252 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
253 awful hack that AC_DEFINEd macro names containing parentheses.
255 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
257 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
258 too drastic, even if Texinfo in theory requires it for info mode.
260 (config.status Invocation): Renamed back from Recreating a
261 Configuration).
262 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
263 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
265 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
267 * NEWS: Version 2.61a.
269 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
270 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
272 * NEWS: Document changes with echo and printf, and the lack
273 of limits on the total size of multi-line values of substituted
274 variables, and the AC_FUNC_FSEEKO fix.
276 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
278 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
279 Writing configure.ac.
280 (Autoconf Input Layout): Renamed from configure.ac Layout.
281 (Recreating a Configuration): Renamed from config.status Invocation.
282 (Obsolete Recreation): Renamed from Obsolete config.status Use.
283 (acconfig Header): Renamed from acconfig.h.
284 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
285 (Writing Testsuites): Renamed from Writing testsuite.at.
286 (Autom4te Cache): Renamed from autom4te.cache.
288 * BUGS: Remove mention of VPATH problem, since it's now documented
289 not to be a bug in the Autoconf build procedure itself, but rather
290 a problem with the proprietary `make' programs.
292 * doc/autoconf.texi (Build Directories): Add a cross reference
293 to VPATH and Make.
295 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
296 * doc/standards.texi: Sync from gnulib.
298 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
299 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
300 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
301 generated automatically.
303 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
305 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
306 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
307 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
309 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
311 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
312 `CEOF$ac_eof' special marker, the awk script cannot contain a
313 line matching `^CEOF', so this is not needed any more.
314 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
315 special marker in the test.
317 2006-12-06 Stepan Kasal <kasal@ucw.cz>
319 * tests/tools.at (autom4te preselections): Use `find -newer';
320 remove one of the sleeps.
322 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
323 more readable, using ...
324 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
326 * doc/autoconf.texi (autoheader Invocation): Do not double-
327 quote the parameter of `AH_BOTTOM' in the example.
329 2006-12-05 Stepan Kasal <kasal@ucw.cz>
331 * doc/autoconf.texi (Configuration Headers): Remove the
332 example with multiple input files.
333 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
334 multiple input files.
336 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
338 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
339 creating the awk substitution script, handle one input line at a
340 time, so that the maximum length of a substituted (multi-line)
341 value is not limited by the size of the sed pattern space.
342 The trade-off is a slightly repetitive sed script.
343 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
344 can only have up to 7 characters, due to Solaris 10 /bin/sed.
345 * tests/torture.at (Substitute a 2000-byte string): Increase the
346 test with several long lines, they should not be caught by sed
347 limits any more.
349 * tests/tools.at (autom4te preselections): New test, to flag
350 entries missing from autom4te.cfg.
351 Report by David Byron <dbyron@hheld.com>.
353 * tests/torture.at (Substitute a 2000-byte string): Actually use
354 AC_PROG_AWK, so the last change works as intended.
355 (Substitute and define special characters): Likewise.
356 (Substitute a newline): Likewise.
358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
359 instead of `awk' consistently.
360 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
361 * tests/torture.at (Torturing config.status): Test both the
362 result of AC_PROG_AWK and plain awk.
363 (Substitute a 2000-byte string): Likewise.
364 (Substitute and define special characters): Likewise.
365 (Substitute a newline): Likewise.
367 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
369 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
370 can be assigned to a function pointer. Problem reported by
371 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
372 part of a patch by Ralf Wildenhues in that same bug report.
374 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
376 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
377 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
379 2006-12-01 Eric Blake <ebb9@byu.net>
381 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
382 cross-compiling from cygwin to mingw.
383 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
384 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
385 to lib/autoconf/c.m4.
387 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
389 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
390 string for more reliable failure. Wrap the entire test that
391 causes the broken Solaris printf to dump core, in a subshell,
392 so the segmentation fault message is reliably suppressed.
393 Fix shell expansion errors by using /usr/ucb/echo always;
394 avoid an error on systems without it by another subshell.
395 Avoid m4 expansion of `$1'. Set the zeroth argument of the
396 subshell-$as_echo to `as_echo', for better error message.
398 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
401 `BASH_SOURCE' contain a newline, set them to empty, as they may
402 not be unset.
404 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
406 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
407 years and is too hard to maintain now. The last straw was
408 reported by Jerker Baeck in
409 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
410 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
411 * doc/autoconf.texi (Particular Functions): Move
412 AC_FUNC_SETVBUF_REVERSED from here...
413 (Obsolete Macros): ... to here. Say that it does nothing now.
414 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
415 Turn into (almost) a no-op.
417 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
418 (AC_C_VOLATILE):
419 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
420 These macros are obsolescent and new applications shouldn't need them.
421 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
422 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
423 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
424 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
425 (AC_FUNC_VPRINTF): Likewise.
426 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
427 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
428 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
430 * doc/autoconf.texi (Setting Output Variables): Mention that
431 @VAR1@VAR2 has unspecified behavior. Problem reported by
432 Ralf Wildenhues.
433 * NEWS: Mention this.
435 * Makefile.am: Put only a single '#' into the copyright notice,
436 so that it's also present in the output file. Standardize wording
437 in makefile copyright notices to match GNU coding standards.
438 * bin/Makefile.am: Likewise.
439 * doc/Makefile.am: Likewise.
440 * lib/Makefile.am: Likewise.
441 * lib/freeze.mk: Likewise.
442 * lib/autoconf/Makefile.am: Likewise.
443 * lib/autoscan/Makefile.am: Likewise.
444 * lib/autotest/Makefile.am: Likewise.
445 * lib/m4sugar/Makefile.am: Likewise.
446 * man/Makefile.am: Likewise.
447 * tests/Makefile.am: Likewise.
448 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
449 one-line file.
451 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
453 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
454 in the sed script that mangles the awk script: delete up to the
455 first exclamation mark only.
456 * tests/torture.at (Substitute and define special characters):
457 Test '!' too.
459 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
461 Rewrite config files generation: avoid quadratic growth in
462 the number of substituted variables by using awk instead of sed
463 for the bulk of the substitutions.
464 * NEWS: Mention this.
465 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
466 forbidden in the output (and thus input) file.
467 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
468 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
469 generate just one large awk script for substitutions,
470 eliminating much of the earlier complexity, while adding some
471 new complexity. Only expand the substitution templates at
472 configure time, for smaller configure script size. If
473 _AC_SUBST_FILES are used, test 'awk' for working getline support
474 at config.status time. If absent, interpolate through the
475 shell. The awk script was written with much help
476 from Paolo Bonzini and Paul Eggert.
477 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.

479 (_AC_SUBST_CMDS): Renamed from...
480 (_AC_SED_CMDS): ...this.
481 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
482 * tests/torture.at (Substitute a 2000-byte string): Also
483 substitute a line with 1000 words, and a variable with several
484 long lines.
485 (Substitute and define special characters): Test awk special
486 characters, and put substitution input strings `@foo@' in the
487 output, to test that no recursion happens; test several other
488 combinations from Paolo Bonzini.
490 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
492 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
493 that replaced echo with AS_ECHO where this wasn't necessary.
494 Problem reportd by Ralf Wildenhues.
495 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
496 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
497 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
499 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
501 * lib/freeze.mk (GREP): Removed, no need to initialize this.
503 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
505 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
506 that traditional Awk lacks 3-arg "split". It has it.
507 Mention that FS must be a single character, and a few other
508 99-byte limits of traditional Awk.
509 Mention that if (i in a) doesn't work with traditional Awk.
511 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
513 * tests/autotest.at (BSx641-newline in command):
514 (BS-BS-newline in command, BSx640-newline in command):
515 (Newline-CODE-BS-newline in command):
516 (Single-quote-BS-newline in command):
517 (Single-quote-newline-BS-newline in command):
518 Use printf '%s\n' instead of echo, for portability to hosts
519 where echo interprets backslashes. This will break on hosts
520 that lack printf, but for now let's assume all such hosts
521 are dead (if not, we should get reports of test failures).
523 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
525 'echo' has some portability problems, when given a first argument
526 with a leading '-', or when given any argument containing '\'.
527 Avoid using 'echo' in these cases.
528 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

552 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
553 * bin/autoconf.as: Redo verbose flag implementation, as the old
554 scheme wouldn't work with AS_ECHO.
555 * lib/autotest/general.m4 (AT_INIT): Likewise.
556 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
557 Don't use ECHO_T, since ECHO_N is now reliable.
558 * lib/autotest/general.m4 (AT_INIT): Likewise.
559 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
560 rather than using a here-document to put the script into a file.
561 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
562 use AS_ECHO.
563 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
564 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
565 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
566 bug, but we might as well stop using ECHO_N and ECHO_C internally.
567 * lib/autotest/general.m4 (AT_SETUP): Likewise.
568 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
569 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
570 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
571 operand, as AS_ECHO requires. Avoid double file name expansion.
572 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
573 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
574 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
575 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
576 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
577 Double-quote strings that would otherwise contain M4 comments.
578 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
580 * configure.ac (AC_INIT): Bump to 2.61a.
581 * NEWS: Likewise.
583 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
585 Version 2.61.
587 * configure.ac (AC_INIT): Bump to 2.61.
588 * NEWS: Likewise.
590 * tests/autotest.at (Macro with backslash in a test title):
591 Comment out for now, as this tests neither fails nor passes
592 reliably. Problem reported by Ralf Wildenhues.
594 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
596 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

676 and Paul Eggert <eggert@cs.ucla.edu>
678 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
679 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
680 ./micro-suite.
682 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
684 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
685 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
686 Imported from a similar patch to gnulib by Bruno Haible.
688 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

704 Automake 1.10 nor future Automake 11.1 (sic).
706 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
707 and Stepan Kasal <kasal@ucw.cz>
709 Handle special characters in test case titles correctly.
710 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
711 properly.
712 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
713 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
714 argument. Extend to check titles printed by ./micro-suite and
715 ./micro-suite -l and the title in micro-suite.log.
716 (Backquote in a test title,
717 Single-quote in a test title,
718 Double-quote in a test title): Don't expect failure anymore.
719 (Backslash in a test title): Put a non-whitespace character after the
720 backslash so that Bourne shells might actually see it as an escape
721 sequence.
722 (Brackets in a test title,
723 Pound in a test title,
724 Comma in a test title,
725 Quoted Macro in a test title,
726 Macro in a test title,
727 Macro with single-quote in a test title): New tests.

729 Macro with double-quote in a test title,
730 Macro with backslash in a test title): New tests expected to fail.
731 * tests/torture.at (#define header templates): M4-quote this title in
732 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
733 The visible effect was a stray [] in the testsuite output.
735 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
737 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
738 `trap ... 0' inside a function, for AIX sh.
740 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
742 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
743 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
744 5363) simply issues a warning when dividing by zero at compile
745 time. Problem reported by Elias Pipping.
747 2006-10-26 Eric Blake <ebb9@byu.net>
749 * THANKS: Update.
750 * doc/autoconf.texi (Evaluation Macros): Improve the example to
751 show effect on macros that expand with commas.

776 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
778 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
779 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
780 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
781 reported by Nelson H. F. Beebe for Coreutils 6.4.
783 * tests/tools.at (autoconf --trace: user macros): Remove test
784 for tracing multiline macros, since m4 1.4.7a uses a different
785 way to number lines. Problem reported by Ralf Wildenhues.
787 2006-10-24 Stepan Kasal <kasal@ucw.cz>
789 * bin/autom4te.in (handle_m4): Do not redirect stdin to
790 /dev/null since the heuristics for interactive behaviour was
791 fixed in CVS m4.
793 * bin/autom4te.in: With --force, always refresh the output
794 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

815 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
816 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

836 Standards.

847 looking for special shell characters.
848 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
849 macro defined by AS_VAR_PUSHDEF before passing it as a
850 parameter.

861 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
863 (Imported from Automake.)
864 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
865 which incorrectly sets the mode of an existing destination
866 directory. In some cases the unpatched install-sh could do the
867 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
868 system. We hope this is rare in practice, but it's clearly worth
869 fixing. Problem reported by Alex Unleashed in
870 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
871 Also, don't bother to check for -m bugs unless we're using -m;
872 suggested by Stepan Kasal.

894 2006-09-16 Karl Berry <karl@gnu.org>
895 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
896 to avoid sectioning errors.
898 Import these changes from Texinfo:

904 (\lquoteexpand, \quoteexpand): new defs.
905 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
906 (\code): must use new \...Char values, since now ` is active.

918 2006-10-13 Stepan Kasal <kasal@ucw.cz>
920 * doc/autoconf.texi (Autoheader Macros): Warn that the text
921 added to the template can get mangled.
923 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
925 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
926 include the default headers, and redefine obstack_chunk_alloc
927 and obstack_chunk_free. Fixes false failure with glibc.
929 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
931 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

950 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
951 Use a better substitute, by inspecting the output of "ls"
952 rather than just using ":".
953 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
954 rather than AS_EXECUTABLE_P, since we needn't worry about
955 non-regular files here.
957 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
958 due to configuration hassles with this. See Tonya Underwood's report
959 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
960 * doc/autoconf.texi (Special Shell Variables): Likewise.
962 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
963 Stepan Kasal <kasal@ucw.cz>
965 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
966 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
968 2006-10-11 Stepan Kasal <kasal@ucw.cz>
970 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
971 initialization which is not inherited through the environment
972 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
973 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
975 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
977 * doc/autoconf.texi (Limitations of Usual Tools): Describe
978 problems with mkdir -p -m.

982 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
983 comment about ac_cpp_err; it was incorrect, and anyway
984 ac_cpp_err is being removed below.
985 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
986 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
987 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
988 nobody uses it.
989 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
990 with werror_flag and conftest.err and so forth. This is more
991 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
992 and anyway the user shouldn't normally want to see this gorp logged.
993 Problem reported by Ralf Wildenhues.
994 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
995 empty, not 'no', since the rest of the code uses 'test -z'.
997 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
999 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1000 Use a single call to AC_DO_TOKENS rather than multiple, for
1001 efficiency.
1002 (_AC_LINK_IFELSE): Test that resulting file is executable.
1003 Problem reported by mwoehlke in
1004 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
1006 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
1007 than creating a file to use with test -x; this is much faster.
1009 2006-10-02 Bruno Haible <bruno@clisp.org>
1011 * lib/autom4te.in (Automake-preselections): Add
1012 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
1014 2006-09-27 Stepan Kasal <kasal@ucw.cz>
1016 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
1017 standard error, `experr' should be used, not `expout'.
1019 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1021 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
1022 fseeko testing program twice; just use the earlier result.
1023 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
1024 Set cache var to 'unknown' (not 'no') if leaving the macro unset
1025 still doesn't let the program compile.
1026 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
1027 failed.
1029 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
1030 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
1031 include it, without including anything else.
1032 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
1033 expressions.
1034 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
1036 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1038 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
1039 `error.h', and include it, for a `error_at_line' prototype.
1040 Use a nonempty format string in the link test.
1041 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
1042 for a declaration of wait3.
1044 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
1046 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
1047 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
1048 can apply to constants too, and that it checks for macro defns.
1049 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
1050 and simply cast the identifier to void. This handles structure
1051 values. Problem reported by Ralf Wildenhues.
1052 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
1054 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1056 * tests/semantics.at (AC_CHECK_DECLS): Also check macros,
1057 structure, and function symbols.

1086 * lib/autoconf/fortran.m4 (AC_PROG_F77, AC_PROG_FC): Likewise.
1087 Report by Olly Betts.

1108 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
1109 --error-output, to avoid warnings with M4 2.0.
1111 2006-09-19 Stepan Kasal <kasal@ucw.cz>
1113 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

1124 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Remove a
1125 mistaken comment: the path has to be relative; do not use
1126 the path at runtime.
1128 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1130 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

1140 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1141 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
1142 for the existence of the directory at configure-time. That's
1143 too late, anyway. Problem reported by Stefan Seefeld.
1145 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1146 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1147 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1149 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1151 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1152 works with GNU M4 1.4.3 again; make the normalized form
1153 match the current m4 message; fix the description.
1154 * test/tools.at (autom4te cache): Adapt to the change.
1156 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
1158 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
1159 to catch glibc bug 2821
1160 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1162 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1163 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1164 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1165 assume C89.

1187 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1188 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1189 accept files with extension `.f'. For consistency, also prefer
1190 xlf over f77.
1191 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
1192 from last patch.

1213 except the first two arguments are reversed.
1214 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1215 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer

1263 deal with LEXLIB.
1264 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1265 didn't work if some values were cached but not others. Test for
1266 broken lex libraries like native ia64-hp-hpux11.22; see
1267 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1268 work around the problem by preferring an empty LEXLIB to -lfl or
1269 -ll. Let the user set LEXLIB='' to indicate no library needed.
1271 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.

1387 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1388 pacify insanely picky compilers. Problem reported by Eric Blake.
1390 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1391 longer supported by Sun.
1393 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1395 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1396 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1397 -Wundef -Werror". Problem reported by David Fang in
1398 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1399 * doc/autoconf.texi (Header Templates, Default Includes):
1400 (Particular Functions, Generic Functions, Header Portability):
1401 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1402 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):
1403 (Present But Cannot Be Compiled, Preprocessor Symbol Index):
1404 Prefer #ifdef to #if.
1405 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prefer #ifdef to #if.
1406 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, _AC_FUNC_MALLOC_IF):
1407 (AC_FUNC_MKTIME, AC_FUNC_MMAP, _AC_FUNC_REALLOC_IF):
1408 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETVBUF_REVERSED, _AC_FUNC_VFORK):
1409 Likewise.
1410 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):

1412 * lib/autoconf/specific.m4 (AC_DECL_SYS_SYGLIST):
1413 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
1414 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1415 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1416 this.
1418 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1420 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1421 problems with arg script text that doesn't end in newline, and
1422 with '-e a...'. Problems reported by Ralf Wildenhues.
1424 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1426 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1427 check for libXt by a check for libX11.
1429 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1431 * doc/autoconf.texi (config.status Invocation): Adjust according
1432 to last change.
1434 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1436 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1437 --help' should mention that `--version' outputs configuration
1438 settings. Report by Bruno Haible.
1440 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1442 Fix test suite failures reported by Pierre in
1443 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1444 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1445 the compiler created a file "b.out" when it didn't create anything
1446 at all.
1447 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1448 Discard stderr too, when invoking the test script.
1450 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1452 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1453 in the restoring of the werror flag.
1455 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1457 * doc/autoconf.texi (Volatile Objects): Be even a little
1458 less skeptical about "volatile", after discussion with
1459 Bruno Haible on bug-gnulib.
1460 (Limitations of Usual Tools): Warn about sed stripping
1461 leading white space from text. From Bruno Haible.
1463 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1465 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1466 compiler complains about it, even if things works after the
1467 complaint. Problem reported by Peter O'Gorman.
1469 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1470 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1471 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1473 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1475 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1476 after -R regardless of host. Patrick Welche reports that this
1477 fixes things on NetBSD 3.99.
1479 * NEWS: Recommend M4 1.4.5.
1480 * README: Likewise.
1481 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1482 * tests/tools.at (autom4te cache): Update wording of diagnostic
1483 to match M4 1.4.5.
1485 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1487 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1488 under AC_C_VOLATILE.
1489 (Volatile Objects): Be a little less skeptical about what
1490 "volatile" means. Derived from thoughts by Ben Pfaff in
1491 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1493 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1495 * doc/autoconf.texi: Fix some typos.
1497 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1499 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1500 more globally, since the 2006-06-30 patch didn't suffice. Problem
1501 reported by Keith Marshall. Also, don't bother with builddir2,
1502 since it shouldn't be needed any more.
1504 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1506 * doc/autoconf.texi (Generic compiler characteristics):
1507 Document AC_COMPUTE_INT. Fix wrong statements on Default
1508 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1510 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1511 (_AC_COMPUTE_INT): Add obsoletion warnings.
1512 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1513 AC_COMPUTE_INT.
1515 * NEWS: Document change.
1517 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1519 * doc/autoconf.texi (Volatile Objects): New section.
1521 * NEWS: Document previous change.
1523 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1525 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1526 Require that long long int be at least 64 bits wide. C99 requires
1527 this and enough programs depend on it so we should check for it.
1528 Bruno Haible reports in
1529 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1530 that long long int is 32 bits wide with some nonstandard compilers.
1531 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1533 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1535 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1536 to a nonexistent file, so that we don't have to worry about
1537 a local site configuration that doesn't use /usr/local.
1538 Problem reported by Keith Marshall in
1539 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1541 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1543 * doc/autoconf.texi: Be more consistent about using @acronym with
1544 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1545 quite right (it talked about "OSF/Tru64", even though the
1546 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1547 and it even mentioned "OSF 4"!) and at this point there's little
1548 reason to talk about OSF any more, since it died in 1994.
1549 (Specific Compiler Characteristics): Simplify example of
1550 negative-size array.
1551 (File Descriptors): Reorder to make the text flow better.
1552 Remove joke about "appreciate the various levels"; I didn't get it.
1553 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1554 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1555 (File Descriptors, Limitations of Usual Tools):
1556 Tone down the advice against renaming or removing open files.
1557 (Limitations of Usual Tools): Add a new section, on 'rm'.
1559 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1561 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1562 -lXt in LIBS, idea from Karsten Hopp; this was due since
1563 this change:
1565 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1566 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1567 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1568 (which belong to Xt, not X itself). See Debian bug 327655.
1570 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1572 * configure.ac (AC_INIT): Bump to 2.60a.
1573 * NEWS: Update.
1575 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1577 Version 2.60.
1579 * configure.ac, NEWS: Update.
1581 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1583 * config/texinfo.tex: Sync from upstream.
1585 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1586 quadrigraph correctly in traces.
1588 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1589 Fix typos.
1591 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1592 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1593 not defined.
1594 * doc/autoconf.texi (Changed Directory Variables): New node,
1595 to document the whole `datarootdir' business a bit better.
1596 * NEWS: Update.
1597 * tests/torture.at (datarootdir workaround): Extend test.
1598 Prompted by report by Alexandre Julliard.
1600 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1602 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1603 when using default mode of IBM C 6 for AIX. Problem and two-line
1604 fix reported by Larry Jones.
1606 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1608 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1609 about literal '${datarootdir}' if a definition is found in the
1610 output file.
1612 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1614 * NEWS: Use "M4" rather than "m4" when appropriate.
1615 Problem reported by Eric Blake.
1616 * doc/autoconf.texi: Likewise.
1617 Use @acronym around BSD, GCC, and GNU when appropriate.
1618 (Why GNU M4): Renamed from "Why GNU m4".
1619 (Redefined M4 Macros): Mention that Posix
1620 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1621 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1622 to int.
1624 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1626 * bin/autom4te.in (handle_output): Do not forbid the empty
1627 pattern.
1628 * tests/tools.at (autoconf: the empty token): New test.
1630 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1632 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1633 calls, so that we do not care whether they are LIFO or FIFO;
1634 in the m4_wrap, do not check which diversion is the topmost
1635 one, just check that the stack is balanced at the end.
1636 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1637 base diversion forever--pop the previous diversion before
1638 opening the new one; consequently, remove the m4_wrap call.
1639 * lib/autotest/general.m4 (AT_INIT): Likewise.
1640 * tests/m4sugar.at: Do not use
1641 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1643 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1644 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1646 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1647 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1648 Rework example of m4wrap token-pasting trouble so that it doesn't
1649 care whether it's LIFO or FIFO.
1650 Fix some "contrary to"s that are awkward in English.
1652 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1654 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1655 to `yes' instead of `int$1_t' if the type is found, for more
1656 consistent configure output (where $1 is the number of bits).
1657 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1658 Suggested by Bruno Haible.
1660 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1661 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1662 with system headers. Report by Bruno Haible.
1664 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1666 * config/config.guess, config/config.sub: Sync from upstream.
1668 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1669 in order to avoid picking up an older installed frozen m4sh.m4f.
1670 Besides an outdated shell startup, this could have been created
1671 by an earlier M4 version with incompatible frozen file format.
1673 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1675 * README: Recommend m4 1.4.4 instead of 1.4.3..
1676 * doc/autoconf.texi: Likewise.
1677 (Special Chars in Names): Say that $(.FOO) is portable, as
1678 suggested by Stepan Kasal.
1679 (Installation Directory Variables, Build Directories):
1680 (Automatic Remaking, Subdirectories, Fortran Compiler):
1681 (Making testsuite Scripts, Defining Directories):
1682 Quote variable usages better.
1683 (Making testsuite Scripts): Add clean-local rule to makefile
1684 snippet, by Eric Blake.
1685 (Installation Directory Variables): Fix table item font.
1686 Reword slightly to clarify. Generalize advice about
1687 not using special characters to include all file-related
1688 vars, not just VPATH.
1689 (Special Chars in Variables): Warn about special characters in
1690 $(srcdir) too.
1691 (Assignments): Clarify default-value example as suggested by
1692 Ralf Wildenhues in
1693 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1694 (Special Shell Variables): Note leading ./ or ../, as suggested
1695 by Eric Blake.
1696 (Limitations of Builtins): Under cd, warn about CDPATH.
1697 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1698 Ralf Wildenhues.
1700 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1702 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1703 `@var', for texi2html.
1704 (Systemology): Some more word wrapping, for DVI output.
1705 (autom4te Invocation): The short option for `--melt' is `-M',
1706 not `-m'.
1708 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1710 * doc/autoconf.texi: More formatting and English tweaks,
1711 many suggested by Ralf Wildenhues.
1712 Reword to avoid "@code{...}'s" and the like, since it's ugly
1713 with Emacs info mode. discontents -> woes.
1714 Put a few "will"s back. time stamp -> timestamp.
1715 side-effect -> side effect.
1717 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1719 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1720 Warn about $@ not persisting. Problem reported by Julien Danjou in
1721 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1722 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1723 Mention other special chars, too.
1725 2006-06-14 Eric Blake <ebb9@byu.net>
1727 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1729 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1731 * doc/autoconf.texi: Some systematic minor improvements, as
1732 follows. Use "makefile" when talking about makefiles
1733 generally (which might be named "makefile" or "Makefile" or even
1734 "foo.mk"), "Makefile" when talking about a specific makefile
1735 called "Makefile". This unclutters the text from weird quotes
1736 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1737 values" rather than "@var{foo}s" and similar constructs containing
1738 "}s". Use "Make rules" rather than "Makefile rules". Minor
1739 English-language improvements. Change the prefix "sub-" to "sub"
1740 and "re-" to "re".
1741 Put blank lines around examples more consistently.
1742 Avoid "rather" and "very" as intensifiers.
1743 Avoid "will" as an auxiliary.
1744 (Limitations of Make): Split this node into....
1745 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1746 (Leading _ in Macro Names, Backslash-Newline-Newline):
1747 (Backslash-Newline Comments, Long Lines in Makefiles):
1748 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1749 (obj/ and Make, make -k Status, VPATH and Make):
1750 (VPATH and Double-colon, $< in Explicit Rules):
1751 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1752 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1753 New nodes, resulting from splitup of Limitations of Make.
1754 All cross-references changed. Raise the top node from
1755 a section to a chapter, and all subnodes accordingly.
1756 Redo the introductory wording to match the new organization.
1757 (Installation Directory Variables): Use an example that is
1758 closer to what Autoconf actually does. Mention that VPATH's
1759 value should not contain metacharacters or white space.
1760 (Fortran Compiler): Fix a VPATH bug in an example.
1761 (Leading _ in Macro Names): Mention that this problem is no longer
1762 of practical concern.
1763 (VPATH and Make): Reword the advice to make it clearer
1764 that Autoconf and Automake support VPATH in non-GNU make, but
1765 many packages have bugs in this area.
1766 ($< in Explicit Rules): Refer to Build Directories rather
1767 than using a (non-VPATH-safe) example.
1768 (Automatic Rule Rewriting): Mention the sort of disaster that
1769 can ensue with Solaris-style rule rewriting with VPATH.
1771 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1773 * doc/install.texi (Compilers and Options): Weaken the
1774 suggestion to use GNU make for VPATH builds.
1776 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1777 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1779 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1780 in regular expression.
1782 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1784 * doc/autoconf.texi (Installation Directory Variables):
1785 Drop extra @samp from `@table @samp' item.
1786 (Limitations of Usual Tools): Comment fix.
1787 Do not nest @samp just to point to other table items.
1788 (Writing testsuite.at) <AT_CHECK>: The second argument to
1789 `@dvar' is already @samp'ed.
1790 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1791 do not use @var in the second argument.
1793 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1795 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1796 $as_shell.exe too. Problem reported by Andreas Buening in
1797 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1799 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1801 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1802 `unused variable' compiler warning, for `-Wall -Werror'.
1803 Reported by Jaap Haitsma in
1804 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1806 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1808 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1809 case the compiler dumps core. Problem reported for
1810 OpenServer 5.0.7 by Tim Rice in
1811 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1812 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1813 Likewise.
1815 2006-06-06 Tim Rice <tim@multitalents.net>.
1817 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1818 "ERROR" only shows up in "make check" output if there is an
1819 error.
1821 2006-06-06 Eric Blake <ebb9@byu.net>
1823 * tests/tools.at (automatically allowed tokens): Fix typo.
1825 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1827 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1829 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1830 typically overflows on x86 CPUs, even though the C standard
1831 requires otherwise.
1833 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1835 * configure.ac (AC_INIT): Bump to 2.59e.
1836 * NEWS: Update.
1838 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1840 Version 2.59d.
1842 * config/texinfo.tex: Sync from upstream.
1844 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1845 seen, invoke libtoolize with `--ltdl' argument.
1846 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1847 * NEWS: Update.
1848 Suggested by Eric Blake.
1850 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1852 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1853 reported by Ralf Wildenhues.
1854 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1856 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1858 * THANKS: Update.
1860 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1862 * doc/autoconf.texi: Modernize some of the references to Solaris.
1864 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1866 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1867 message issued by AC_REQUIRE.
1868 * tests/m4sugar.at: Check m4_require's error message.
1869 * tests/base.at: Check AC_REQUIRE's error message.
1870 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1871 to...
1872 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1873 AT_CHECK_M4.
1874 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1875 `expout' as the last parameter.
1876 * tests/tools.at: Adapt to the above change.
1878 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1880 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1881 information about race-free implementations of mkdir.

1885 * bin/autoreconf.in (help): Document M4 environment variable.
1886 * bin/autoconf.as (Usage): Likewise.
1887 * bin/autom4te.in (help): Likewise.
1888 * doc/autoconf.texi (autom4te Invocation): Likewise.
1890 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1892 * NEWS: GNU make now recommended for VPATH builds.
1893 Mention that some macros are now documented to be obsolescent.
1894 * doc/autoconf.texi:
1895 Prefer "current" to "modern" to describe
1896 currently-used (albeit perhaps old-fashioned) hosts.
1897 Mention which ancient features no longer need to be worried about.
1898 setgid -> set-group-ID
1899 setuid -> set-user-ID (these are the Posix terms)
1900 Fix some misuses of "only".
1901 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1902 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1903 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1904 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1905 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1906 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1907 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1908 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1909 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1910 Mention that these macros are obsolescent.
1911 (Installation Directory Variables): shall -> should
1912 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1913 Mention that it's now safe to use 3 and 4.
1914 (Limitations of Usual Tools): cp -r is now specified by Posix.
1915 Omit longwinded and obsolescent discussion of cp -f.
1916 Modernize discussion of expr, ls.
1917 (Limitations of Make): Modernize discussion of VPATH builds.
1918 Mention $? as a workaround in some cases.
1919 * doc/install.texi (Basic Installation):
1920 Mention "./configure; make; make install" first. Be more
1921 specific about why this file is generic. Remove unnecessary
1922 parens. Remove misleading "only". Remove obsolete advice
1923 about csh. Don't say "configure" takes awhile; say it
1924 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1925 and CC=c99 rather than CC=c89, as these are blessed by current
1926 Posix. Recommend GNU make if doing a VPATH build.
1928 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1930 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1931 examples involving shell prompts.
1933 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1934 and Paul Eggert <eggert@cs.ucla.edu>
1936 * doc/autoconf.texi (Here-Documents): Add details about the
1937 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1938 use "here-documents" instead of "here documents".
1940 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1942 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1944 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1946 * doc/autoconf.texi (File System Conventions): Warn about ":"
1947 anywhere in directory names.
1949 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1951 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1952 about quoting the case statement, just in case.
1953 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1954 was fixed in ksh93g; reported by Ralf Wildenhues.
1956 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1958 * doc/autoconf.texi (System Services): Do not document
1959 overriding EXEEXT via ac_cv_exeext=ext.
1960 (Particular Programs) <AC_PROG_MKDIR_P>:
1961 Document that ${MKDIR_P} understands --.
1962 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1963 comment.
1965 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1967 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1968 argument with leading hyphen. Problem reported by Paul Eggert.
1970 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1972 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1973 about quoting ac_try: quote all of it, if any of it seems suspicious.
1974 This means we don't have to worry about ${ or sed any more.
1975 Also, double-quote the case statement, to work around misuses via
1976 underquoting as reported by Ralf Wildenhues in
1977 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1978 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1979 undocumented and dangerous macro.
1980 Problem reported by Ralf Wildenhues in
1981 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1983 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1985 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1986 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1987 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1989 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1991 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1992 since evidently some packages rely on the old, broken behavior.
1993 Problem reported by Ralf Wildenhues in
1994 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1995 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1996 pre-2006-05-26 definitions, but leave in the comments that
1997 these macros are dangerous and should not be used.
1998 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1999 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
2000 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
2001 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
2002 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
2004 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
2006 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
2007 the use of 'tr', since this is our only use of 'tr'.
2009 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2010 and Paul Eggert <eggert@cs.ucla.edu>
2012 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2013 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2015 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2017 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2018 the output file in the `${datarootdir}' test.
2020 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2021 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2023 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2024 mention of `datarootdir' in the input file(s), but literal
2025 `${datarootdir}' in the output file, and we haven't warned yet,
2026 then warn as well: the user may have (erroneously) used
2027 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2028 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2029 * tests/torture.at (datarootdir workaround): Extend this test.
2030 * NEWS: Update.
2032 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2033 and Paul Eggert <eggert@cs.ucla.edu>
2035 * doc/autoconf.texi (autoheader Invocation): The first argument to
2036 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2037 alternatives and clear up the language a bit.
2039 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2041 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2042 ac_config_guess, ac_config_sub, ac_configure.
2043 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2044 Fix typo that prevented an unnecessary space from being removed.
2045 Problems reported by Ralf Wildenhues in:
2046 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2048 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2050 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2051 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2052 Don't use the term "thread-safe" to talk about mkdir race
2053 conditions, since the problem is more a process than a thread
2054 issue. Problem reported by Stepan Kasal in:
2055 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2056 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2057 the test for 'install' more closely. Look at MKDIR_P first.
2058 Look in the PATH, and at /opt/sfw/bin.
2059 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2060 Don't bother to try mkdir -p, since we already check mkdir --version;
2061 just look at the version number. (There's no easy way to check
2062 for race-free implementations.)
2063 * tests/tools.at (autoconf: subdirectories): Adjust to above
2064 changes, since MKDIR_P now might end in "/mkdir -p".
2066 * doc/autoconf.texi (autoheader Invocation): Mention that the
2067 first arg of AC_DEFINE_UNQUOTED must be a literal.
2068 Problem reported by Ben Pfaff in
2069 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2071 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2072 * doc/autoconf.texi (Special Chars in Variables): New section.
2073 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2074 (Installation Directory Variables): Quote $(datadir) better.
2075 (Limitations of Builtins): Describe some of eval's trickiness.
2077 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2078 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2079 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2080 in front of every arg, not just trailing args. Quote apostrophes.
2081 (_AC_EVAL_ECHO): New macro.
2082 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2083 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2084 removed.
2085 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2086 exposed by quoting of eval argument. Put the command on line line
2087 so it logs better.
2088 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2089 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2090 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2091 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2092 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2093 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2094 Use eval more safely.
2095 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2096 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2097 to be replaced.
2098 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2099 lines, exposed by quoting of eval argument.
2101 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2102 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2104 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2105 initialization of `ac_cv_exeext', do not override it if it was
2106 already set, unless it was set to `no', for compatibility with
2107 Autoconf-2.13, and comment this.
2108 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2109 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2110 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2111 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2112 Document that this test may be overridden by setting
2113 `ac_cv_exeext'.
2115 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2117 Revert these two patches:
2119 2006-04-06 Eric Blake <ebb9@byu.net>
2120 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2121 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2122 2006-04-01.
2124 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2125 Clean up _AC_COMPILER_EXEEXT* macros.
2126 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2127 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2128 ac_file to the name of the default output file and call
2129 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2130 initial `rm' of the candidate files...
2131 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2132 the same list in subsequent `rm' calls, and for the temporary
2133 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2134 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2135 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2136 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2137 no longer needed) by libtool. Make it a cache check.
2138 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2139 copied here by mistake.
2140 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2141 _AC_COMPILER_EXEEXT.
2142 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2143 _AC_COMPILER_OBJEXT directly.
2144 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2146 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2148 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2149 Fix description of how the buggy `sed' works.
2151 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2153 Sync from Automake:
2155 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2156 ENOLCK. Only mention `make -j' when applicable. Only raise
2157 fatal errors when `make -j' is involved. Improve error message.
2159 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2161 * doc/autoconf.texi (Here-Documents): We now know more about
2162 the variable expansion in here documents bug.
2163 Thanks to Tim Rice and Stepan Kasal.
2165 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2166 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2168 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2170 * tests/autotest.at (Multiline command from M4 expansion):
2171 No failure to be expected if the shell quotes newlines in
2172 commands in the `set -x' output. Report by Tim Rice.
2173 * THANKS: Update.
2175 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2177 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2178 expansion in the here-documents used by config.status, as that
2179 runs afoul of the Korn shell version M-12/28/93d bug described in
2180 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2181 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2182 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2184 2006-05-23 Jim Meyering <jim@meyering.net>
2186 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2187 Fix typo introduced with 2006-04-02 change. It reversed the sense
2188 of the test.
2190 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2192 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2193 ac_dB slightly, to save bytes in the script.
2194 Max out at 50 lines, rather than 96; this is more likely
2195 (though not guaranteed) to avoid obscure 'sed' failures.
2197 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2199 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2200 `tr -d -' as bad option argument. Work around this by deleting
2201 an unrelated character.
2202 Report by Tim Rice <tim@multitalents.net>.
2204 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2205 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2206 Stepan Kasal <kasal@ucw.cz>
2208 * doc/autoconf.texi (Particular Programs): Do not promise that
2209 we always prefer the GNU version of the program, and that we
2210 search according to PATH; both rules can have exceptions.
2211 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2212 AC_PROG_SED. Move descriptions of limitations
2213 to the Limitations of Usual Tools section.
2214 (Limitations of Usual Tools) <sed>: Mention script length
2215 limitations with Solaris /usr/ucb/sed.
2216 <grep>: Fix wording for empty alternative. Mention that -c and
2217 -l should not be combined, and that -E and -F should not be
2218 combined.
2220 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2221 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2223 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2224 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2226 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2228 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2229 AC_DEFINE is now passed to m4_pattern_allow.
2230 * NEWS: Mention that; likewise for AC_SUBST.
2231 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2232 the parameter to m4_pattern_allow.
2233 * tests/tools.at: Add a check for that.
2235 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2237 * lib/autoconf/status.m4: Fix typos.
2239 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2241 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2242 only the files that this macro generates.
2244 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2246 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2247 the HP-UX sed limitation of 99 commands, labels do not count.
2248 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2249 in the comment.
2250 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2252 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2254 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2255 Import the following fix from coreutils:
2257 2006-01-13 Jim Meyering <jim@meyering.net>
2259 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2260 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2261 not double-quote uses of that variable, to accommodate the rare
2262 case in which getmntent is available in none of the libraries
2263 checked. This happens at least on FreeBSD 5.0.
2265 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2267 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2268 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2269 some other programs unwisely rely on these undocumented vars.
2270 But put in warning comments about them.
2271 Problem reported by Ralf Wildenhues in
2272 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2273 * NEWS: Document that these variables are intended to go away.
2275 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2277 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2278 and set the language to C++ (analogous to the equivalent Fortran
2279 tests).
2281 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2282 * doc/autoconf.texi (C++ Compiler): Document it.
2283 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2284 * NEWS: Update.
2286 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2288 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2289 that caused config.status to generate 100-command sed scripts; the
2290 portable limit is 99.
2292 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2295 variable `ac_d' instead of `d' to avoid infringing namespace.
2296 Report by Ralf Menzel.
2298 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2301 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2302 * tests/tools.at (autoconf: subdirectories): New test, taken from
2303 the corresponding problem report by Ralf Wildenhues in:
2304 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2306 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2307 Quote some uses of shell variables if they might suffer unexpected
2308 globbing. This doesn't fix all instances of quoting problems that
2309 I found, just the easy ones that look safe.
2310 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2311 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2312 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2313 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2314 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2315 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2317 Likewise.
2318 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2319 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2321 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2323 * bin/autoreconf.in ($help): Reword according to the manual.
2324 Suggested by Olly Betts.
2326 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2327 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2329 * bin/autoreconf.in: Pass the directory argument to
2330 `require_configure_ac'. Fix comment.
2331 * tests/torture.at (Configuring subdirectories): Expose this.
2332 Reported by Olly Betts.
2334 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2336 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2337 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2338 Automake as follows:
2340 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2341 `$configure_in' instead of `configure.in', to preserve
2342 directory component.
2344 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2346 * config/config.guess, config/config.sub, config/texinfo.tex,
2347 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2349 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2351 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2352 test for C99 conformance; (bool) 0.5 is an integer constant
2353 expression, but (bool) -0.5 is not. Problem reported by Fedor
2354 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2356 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2358 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2359 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2360 Warn about obsolete install-sh files. Remove stray sentence
2361 fragment and fix cross reference.
2362 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2363 install -d; this undoes the 2006-05-10 change.
2364 (MKDIR_P): Mark with AN_MAKEVAR.
2365 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2366 that we don't require $INSTALL to be thread-safe. Move comments
2367 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2368 of AC_PROG_INSTALL. Output a message saying that we're checking
2369 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2370 MKDIR_P instead of AC_SUBST.
2371 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2372 Special magic for MKDIR_P, too.
2373 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2374 a dnl.
2375 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2377 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2379 Sync from Automake, as follows:
2381 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2382 * config/install-sh: Initialize IFS, so field splitting isn't
2383 turned off later.
2384 * config/mkinstalldirs: Likewise.
2385 * config/missing: Remove superfluous quotes. Replace all uses of
2386 `[' by `test', for consistency, and for..
2387 * config/missing (sed_minuso, sed_output): New variables.
2388 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2389 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2390 Fixes `missing' to detect `--output' for help2man. Fixes
2391 PR automake/483. Report by Dennis J. Linse.
2392 (autom4te): Document in `missing --help'.
2394 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2396 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2397 * config/install-sh: Don't use 'path' to talk about file names,
2398 as per GNU coding standards. Close a race condition reported by Ralf
2399 Wildenhues and Stepan Kasal. There is still a race condition
2400 on hosts that predate Posix 1003.1-1992, but we can't help this.
2401 Don't mishandle weird characters like space on pre-Posix hosts.
2402 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2403 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2404 AC_PROG_MKDIR_P from AS_MKDIR_P.
2405 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2406 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2407 earlier editions are not (including Automake 1.8.3).
2408 Do not suggest mkinstalldirs for thread-safety.
2409 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2410 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2411 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2412 presence of special characters and race conditions.
2413 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2414 in Autoconf's name space.
2416 2006-05-10 Bruno Haible <bruno@clisp.org>
2417 and Paul Eggert <eggert@cs.ucla.edu>
2419 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2420 from Automake with minor changes.
2421 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2423 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2425 * config/install-sh: Update to Automake CVS version, as follows:
2426 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2427 * lib/install-sh: Simplify the expr implementation of dirname.
2428 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2429 * lib/install-sh: Handle --, and diagnose unknown options.
2431 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2433 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2434 `./autom4te' to create `./testsuite', since the `all' target
2435 will ensure its presence, but `installcheck' should not create
2436 the uninstalled wrappers.
2438 * tests/torture.at (Unusual Automake input files): Skip if we
2439 detect automake < 1.8.
2441 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2443 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2444 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2445 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2446 * NEWS: Update.
2448 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2450 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2451 munge (multiple) white space and other oddities.
2452 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2453 single quotes in variable assignment.
2454 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2455 and similar failures by adding multiple spaces, tabs, and other
2456 special characters.
2457 Report and different test suggested by Francesco Romani
2458 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2460 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2461 single quotes, we only need to search for single quotes; this
2462 both simplifies the search pattern, and makes us less
2463 susceptible to `echo' variations for arguments not containing
2464 single quotes.
2465 (_AC_ARG_VAR_VALIDATE): Likewise.
2467 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2469 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2470 `$*' and IFS concatenation issue with traditional shells and
2471 bash-2.04. Report by Seanster@Seanster.com.
2473 2006-05-03 Bruno Haible <bruno@clisp.org>
2475 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2476 precisely which Mac OS X versions have the od problem.
2478 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2480 * doc/autoconf.texi: Use @option systematically.
2482 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2483 and Bruno Haible <bruno@clisp.org>
2485 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2486 about 'od'.
2487 (Integer Overflow): Mention the special case of integer division
2488 overflow.
2490 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2492 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2493 traditional shells like the Solaris one that do not use the
2494 first IFS character for assembling `$*'.
2495 Prompted by a related report from autoconf_bug@nro.ca.
2497 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2498 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2500 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2501 Mention more problems with the -e option.
2503 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2505 * NEWS: Typo.
2506 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2508 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2509 in URLs to improve DVI formatted output (requires texinfo 4.6).
2510 (System Services, Systemology, Shellology): Likewise.
2511 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2512 output.
2514 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2515 continuous text.
2516 (Runtime): Fix macro argument names to match description:
2517 `action-if-found' -> `action-if-true' and similarly.
2518 (Obsolete Macros): Likewise.
2519 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2520 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2521 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2523 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2525 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2527 * ChangeLog: Typo.
2528 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2529 DVI output.

2534 /bin/sh set unsorted output.
2535 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2536 * tests/local.at: Likewise.
2538 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2540 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2541 (Integer Overflow, Null Pointers, Buffer Overruns):
2542 (Floating Point Portability, Exiting Portably): New sections.
2543 (Writing Test Programs): Fix some langauge. Recommend exiting
2544 with status 1, not merely nonzero. Clarify exit declaration.
2545 (Run Time): Move C exit status stuff to new Exiting Portably section.
2546 (Systemology): Mention Posix and levenez. Update v7 reference.
2547 (Portable Shell): Mention the Posix shell.
2549 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2551 * bin/autoconf.as (me): Replace by as_me.
2553 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2555 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2556 since as_me isn't set yet.
2558 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2560 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2561 a few minor bugs in this area.
2563 * doc/autoconf.texi (Programming in M4sh): Comment out the
2564 documentation of AS_BASENAME, for now.
2565 (Shell Substitutions): Do not use AS_DIRNAME in an example.

2567 AS_BASENAME.
2568 * bin/autoconf.as (me): Don't use AS_BASENAME.
2569 (dir): Remove the unused variable.
2570 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2571 AS_DETECT_REQUIRED. All uses changed.

2577 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2578 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2579 (_AS_DIRNAME_PREPARE): Likewise.
2580 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2581 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2582 (AS_DIRNAME): Use "dirname --".
2584 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>

2594 with more accuracy and detail.
2596 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2598 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2599 Archive is not officially `GNU' any more. Update URL.
2600 (Defining Directories): Likewise
2601 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2603 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2605 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2606 newline from the `trap' code to finish `config.log'; the NetBSD
2607 /bin/sh resets the exit status after an empty command, as
2608 documented in doc/autoconf.texi.
2609 Reported by Dalibor Topic <robilad@kaffe.org>.
2611 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2613 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2614 Suggested by Bruno Haible.
2616 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2618 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2619 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2620 Instead, just list the shells that we know work.
2621 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2622 changed. Be more cautious about the _cv_ variable.
2623 * tests/tools.at (Syntax of the shell scripts): Check the
2624 _cv_ variable once, at first, to avoid an internal autoconf error
2625 when sh -n does not work.
2627 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2629 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2631 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2633 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2634 use ">&-" since we're only 99.999% sure that this is portable,
2635 and since the MinGW bug is fixed in a different way.
2636 * lib/autotest/general.m4 (AT_INIT): Likewise.
2638 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2640 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2641 before opening config.log, to avoid hitting a bug on MinGW.
2643 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2645 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2646 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2647 This works around a MinGW bug reported by Eric Paire.
2648 Make sure that all writes to the log file append to it,
2649 rather than possibly losing data.
2650 * lib/autotest/general.m4 (AT_INIT): Likewise.
2652 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2654 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2655 description.
2657 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2659 * NEWS: Update.
2661 * configure.ac (AC_INIT): Bump to 2.59d.
2663 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2665 Version 2.59c.
2667 * Makefile.maint (news-date-check): Do not require a leading `*'
2668 before the release date in NEWS.
2670 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2671 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2673 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2674 the instantiated file do not contain the string 'datarootdir'
2675 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2676 @mandir@, replace the reference '${datarootdir}' by the value.
2677 * tests/torture.at (datarootdir workaround): New test.
2678 * NEWS: Advertise this temporary fixup.
2679 Based on a patch by Bruno Haible, reported and analyzed by
2680 Paul Eggert and Noah Misch.
2682 2006-04-12 Eric Blake <ebb9@byu.net>
2684 * tests/autotest.at (Debugging a failed test): Fix comment.
2686 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2688 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2689 all the changes since 2006-04-07.
2691 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2693 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2694 succeeded, but `ln -s file dir' failed, take care to remove the
2695 leftover target before the next test, to prevent its spurious
2696 failure; also make sure `ln file dir' works before selecting it.
2697 Thanks to Keith Marshall for pointing this out.
2698 * THANKS: Update.
2700 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2701 assignments in `at_debug_args', so that we put them correctly
2702 in the `run' script.
2703 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2704 Reported by Eric Blake.
2706 2006-04-11 Eric Blake <ebb9@byu.net>
2708 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2709 top-level tests after micro-suite has been run. Used in...
2710 (Debugging a successful test, Debugging script and environment),
2711 (Debugging a failed test): ...these new tests. The first of these
2712 is fixed by...
2713 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2714 macro, split out from...
2715 (AT_INIT): ...here, so that using -d also generates a run script.
2716 Document that -d inhibits top-level logging.
2717 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2718 inhibits top-level logging; debug scripts are created.
2720 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2721 check.
2722 * tests/autotest.at (Empty test, Empty check): New test to check it.
2724 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2725 from gcc.
2727 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2729 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2730 the files if a problem appears. Make the empty *.at files
2731 read-only, too. Proposed by Ralf Wildenhues.
2733 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2735 * config/Makefile.am: Add comment to force updated Makefile.in.
2737 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2738 space only patch to this file, this patch causes the Makefile.in
2739 files that include freeze.mk to be updated, and thus have a
2740 newer time stamp again, which in turn makes a pristine CVS
2741 checkout have correct time stamps.
2743 * Makefile.maint (cvs-sv): New macro, to be used..
2744 (config.guess-url_prefix, config.sub-url_prefix)
2745 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2746 point to CVS text checkout of Gnulib files.
2747 (copyright-check): Bump current year.
2748 (announcement): Do not hard-wire `./announce-gen'.
2749 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2750 correctly.
2751 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2752 `chmod +x'.
2753 (wget_files): Update config.guess, config.sub, texinfo.tex by
2754 `wget-update', now that their URLs work again.
2756 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2758 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2759 Problem noted by Paul D. Smith.
2761 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2763 * doc/autoconf.texi: Remove unused words from word list.
2764 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2765 .x-sc_trailing_space: New files.
2767 * doc/standards.texi: Sync from gnulib.
2769 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2770 `LIBOBJDIR' as experimental.
2772 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2773 with a target directory; it's internally implemented as `cp'
2774 anyway, but since Autoconf advertises the possibility to use
2775 a target directory when LN_S is `ln -s', we need to find out.
2776 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2777 analyzed by Keith Marshall <keith.marshall@total.com>.
2779 * THANKS: Update.
2781 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2783 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2784 confdefs.h as-is. In general, if it has backslash-newline or the
2785 like, then it doesn't work either to sort or to remove empty
2786 lines.
2788 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2790 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2792 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2794 * lib/autom4te.in (Automake-preselections): Preselect
2795 _AM_SUBST_NOTMAKE.
2797 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2799 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2800 apostrophe within a single-quoted string, as this is the usual
2801 tradition and is easier to read than '"'"'. Don't rely on the
2802 shell treating "$/" like '$/'. Use a more-consistent indenting
2803 style for the trap.
2805 2006-04-09 Eric Blake <ebb9@byu.net>
2807 * tests/autotest.at (Backquote command substitution),
2808 (Multiline backquote command substitution): Remove mistaken
2809 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2810 applied...
2811 (Parenthetical command substitution, Multiline parenthetical
2812 command substitution): here.
2814 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

2832 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2833 Gnulib section.

2844 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2845 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2846 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2847 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2848 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2849 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2850 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2851 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2852 (Coding Style). Don't mention m4_expand_once.

2863 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2864 Catch a bug in an HP-UX C compiler.
2865 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2866 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

2870 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2871 New macros.
2873 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2874 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2876 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2878 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2879 of the warning introduced by the 2001-08-28 change.
2881 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2887 that contains braces.
2889 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2891 Revert the patch from 2006-04-01 and only improve
2892 _AS_DETECT_BETTER_SHELL:
2894 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2895 skip nonexistent directories.
2896 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2897 only shell candidates which exist.
2898 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2899 * lib/autotest/general.m4 (AT_INIT): No need to give three
2900 parameters to _AS_PATH_WALK.
2902 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2903 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2905 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2906 distinguish m4sugar macros.
2907 * tests/tools.at (autoupdating with aclocal and m4_include):
2908 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2909 test case by Noah Misch <noah@cs.caltech.edu>.
2911 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2913 Revert my change from 2006-03-17, in other words:
2914 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2915 and DUALCASE=1.
2916 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2917 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2918 it is set.
2920 2006-04-07 Eric Blake <ebb9@byu.net>
2922 * doc/autoconf.texi (Programming in M4sh): Document that
2923 AS_MKDIR_P exits the script on failure.
2924 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2926 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2928 * config/elisp-comp, config/install-sh, config/mdate-sh,
2929 config/missing, config/mkinstalldirs: Sync from Automake.
2931 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2932 from Automake.
2934 * doc/make-stds.texi: Sync from gnulib.

2938 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2939 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

2943 Eric Blake <ebb9@byu.net>,
2944 Paul Eggert <eggert@cs.ucla.edu>,
2945 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2947 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2948 whether `set' quotes correctly: redirect stderr of the tested
2949 `set', and use a subshell, for Ultrix; use `sed' instead of
2950 `grep' for zsh `set' which may write binary output; match only
2951 at the beginning of a line, to avoid false positives.
2952 In order to avoid false positives by unrelated variables with
2953 multiline content, put the dump algorithm in a subshell and
2954 unset all variables containing newlines (except some which are
2955 special to the shell). Warn about cache variables that are
2956 unset.
2958 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2960 * config/config.guess, config/config.sub, config/texinfo.tex:
2961 Sync from upstream.
2963 * tests/mktests.sh: Reword comments.
2965 * tests/mktests.sh: Only skip internal macros starting with
2966 `_AC_' or `__AC_'. Noted by Stepan Kasal.

2968 (AC_ARG_VAR): Do test this now.
2969 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2970 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2971 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2972 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2974 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2975 shell issue with double-quoted command substitutions of native
2976 commands.
2977 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2978 Marshall.
2980 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2988 (sc_tight_scope): Do not fail for non-existing `src' directory.
2989 (sc_changelog): Skip the Copyright footer.
2990 * lib/autoconf/lang.m4: Remove trailing space.
2992 * lib/autoconf/status.m4: More replacements to
2993 <tab><space> where this makes sense.
2995 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2997 * tests/Makefile.am (maintainer-check-posix):
2998 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
3000 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
3001 ac_config_<foo>s again, sometimes normalized, sometimes not.
3002 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
3003 (AC_CONFIG_COMMANDS): Do not do so here.
3004 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
3005 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
3006 2005-07-25 rewrite. Noticed by Noah Misch.
3008 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
3009 _AC_PRESERVE_HELP_ORDER, ...
3010 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
3012 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
3013 inside m4_expand_once; it is redundant.
3015 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
3016 for --help from Cygnus `configure.'
3018 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
3020 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
3021 on a patch proposed by Ralf Wildenhues.
3023 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3025 * lib/autoconf/status.m4: Replace <space>''<tab> with
3026 <tab><space> where this makes sense.
3028 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
3029 Noah Misch <noah@cs.caltech.edu>
3031 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
3032 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
3033 * doc/autoconf.texi (Help Formatting): New node.
3034 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
3036 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3038 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
3039 lib/autoconf/specific.m4, lib/autoconf/status.m4,
3040 lib/autoconf/types.m4, lib/autotest/general.m4,
3041 tests/mktests.sh, tests/torture.at: White space cleanup:
3042 remove some SPACE before TAB, or add quoting ('' or @&t@).
3044 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
3046 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
3048 2006-04-05 Eric Blake <ebb9@byu.net>
3050 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
3051 empty test suite works.
3052 * tests/autotest.at (Empty test suite): Remove xfail.
3054 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3057 TAGS to ac_config_<foo>s.
3058 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3059 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3060 normalizing it, consistent it with previous releases.
3061 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3063 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3065 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3066 Use simplified args that Eric Blake originally suggested.
3068 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3070 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3071 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3072 Use 'comm' rather than N instances of grep; this also fixes a bug
3073 whereby substrings were incorrectly matched, causing us to not
3074 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3075 (exclude_list): Exclude empty macros.
3076 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
3078 Use awk rather than grep -E or egrep, to avoid
3079 portability problems with regular expressions containing newlines.
3080 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
3081 Switch from grep to awk syntax.
3082 (ac_exclude_script): Renamed from ac_exclude_egrep.
3083 (au_exclude_script): Renamed from au_exclude_egrep.
3085 2006-04-04 Noah Misch <noah@cs.caltech.edu>
3087 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3088 a subdirectory subject to Cygnus `configure'.
3089 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3091 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3092 report request when we have no AC_PACKAGE_BUGREPORT.
3094 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3096 * THANKS: Update.

3099 generated files.
3101 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
3102 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a

3113 (output): Emit AC_CONFIG_SUBDIRS as needed.
3114 * tests/autoscan.at (autoscan): Remove XFAIL.
3116 2006-04-03 Noah Misch <noah@cs.caltech.edu>
3118 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
3120 2006-04-03 Eric Blake <ebb9@byu.net>
3122 * THANKS: Add myself.
3124 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3126 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3127 to log, point to testsuite output tree.
3129 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3131 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

3136 Remove; all uses removed.
3137 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3157 Clean up _AC_COMPILER_EXEEXT* macros.
3159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3160 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3161 ac_file to the name of the default output file and call
3162 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3163 initial `rm' of the candidate files...
3164 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3165 the same list in subsequent `rm' calls, and for the temporary
3166 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3167 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3168 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3169 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3170 no longer needed) by libtool. Make it a cache check.
3171 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3172 copied here by mistake.
3173 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3174 _AC_COMPILER_EXEEXT.
3175 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3176 _AC_COMPILER_OBJEXT directly.

3211 subordinate tools.
3212 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
3213 * doc/autoconf.texi (autoreconf Invocation): Document it.
3215 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

3247 2006-04-01 Stepan Kasal <kasal@ucw.cz>
3249 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3250 switch all of them on and of when necessary. Fixes the bug when
3251 m4sugar macros (e.g., m4_define) were expanded after the first
3252 automatic update (e.g., after AC_PREREQ or AC_INIT).
3254 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3508 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3509 newline for portability.
3510 * tests/torture.at (Torturing config.status): Also test 100

3950 by the function rather than ignoring it.
3951 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3952 comparing its address. Intel's interprocedural optimization was

3971 Stepan Kasal <kasal@ucw.cz>
3973 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3974 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3975 make its content writable before removing it. Remove an errorneous
3976 comment from the end, where the logs of the failed tests are copied
3977 to the main log file.

3986 problems if the testsuite were running too fast.
3988 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>

4002 suggested by Ben Elliston. Handle weird characters correctly.
4004 2005-09-06 Stepan Kasal <kasal@ucw.cz>
4006 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
4007 calls, so that the final expansion of this macro is shorter.
4008 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
4009 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
4010 the cleanup there. Use AS_VAR_* macros, to be more general.
4011 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4013 * lib/autoconf/general.m4: Use AS_IF where appropriate.

4037 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4038 "if $undefined_var;" succeeds with my shell.
4040 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4041 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

4057 Stepan Kasal <kasal@ucw.cz>

4060 first header appears, define AH_HEADER.
4061 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4062 Update limitations about when to call AC_CONFIG_HEADERS.
4063 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4064 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4065 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4066 ``Configuration Actions''; fix their index entries.
4068 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4069 options correctly. Process N-M as M-N if M is smaller than N.
4070 Process ranges correctly so that N-N will run only N.
4071 Sort and uniquify the tests that will be run. If there is more
4072 than one test, reinsert the banners for the tests.

4078 before passing the macro name to AH_TEMPLATE.
4080 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4081 now opens log after option processing; in particular, --version
4082 and --help do not touch config.log.
4084 * Makefile.maint: Revert the change from 2005-08-12.
4086 2005-08-22 Stepan Kasal <kasal@ucw.cz>
4088 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
4089 common code to...

4094 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
4095 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
4096 Language cleanup.
4098 * doc/autoconf.texi (Defining Symbols, Changed Results):
4099 Prepend to LIBS, not append, in examples.
4101 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4103 When building in place, set srcdir="."; suggested by Tim Van Holder.
4105 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4106 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4107 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4108 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4109 does not mean "no --srcdir option".
4111 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4113 * tests/autoscan.at (autoscan): New file.
4114 * tests/suite.at: Use it.
4115 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
4116 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.

4125 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4127 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4128 was pushdef'ed twice while popped only once. Push it only once.
4129 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4131 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4133 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4138 * Makefile.maint: Update from Bison.
4140 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4141 "<tab>" in comment, so that the point is understandable.
4143 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4145 Rewrite substantial part of lib/autoconf/status.m4.
4146 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4147 and CONFIG_COMMANDS are not processed in four separate loops.
4148 Instead, there is one main loop. This alows that the common code
4149 is expanded only once, thus config.status (and configure) is smaller.
4151 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4152 the AC_LIST_FILES and cousins macros are no longer used.
4154 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4155 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4156 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4157 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4158 contain the initialization, nor the for loop, nor the associated
4159 commands; all these go to ...
4160 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4161 _AC_OUTPUT_CONFIG_STATUS.
4162 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4163 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4164 (_AC_OUTPUT_FILE): The creation of the sed script ...
4165 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4166 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4167 _AC_OUTPUT_MAIN_LOOP.
4168 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4169 _AC_CONFIG_COMMANDS): Use ...
4170 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4171 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4172 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4173 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4174 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4175 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4176 ... new macros.
4177 (_AC_CONFIG_UNIQUE): Update.
4178 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4179 Replaced by this ...
4180 (_AC_LIST_TAGS): ... new common macro.
4181 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4182 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4183 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4184 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4185 this didn't belong to the `config commands' section.
4186 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4187 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4188 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4189 to the `config commands' section either.
4190 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4191 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4193 ... and many changes to the comments nearby.
4195 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4196 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4197 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4198 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4199 (#define header templates): The comment at the top of the generated
4200 header now includes the name(s) of the source file(s).
4202 Several unrelated small changes:
4204 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4205 parameter to AC_DIAGNOSE.
4206 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4207 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4208 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4209 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4210 with AU::AC_OUTPUT.
4211 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4212 in AC_OUTPUT doesn't double-quote it either.
4213 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4214 parameters.
4216 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4218 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4219 versions of Portland Group compiler produce single- and double-quoted
4220 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4221 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4223 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4225 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4226 This is a corrected version of yesterday's patch.
4228 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4230 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4231 path, too; insert a "===" to emphasize the line.
4233 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
4234 ac_cv_build_alias to ac_build_alias.
4235 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4237 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4238 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4239 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4240 (AC_ARG_VAR): ... here.
4241 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4242 target_alias.
4244 Keep a list of all precious variables and process them with one simple
4245 for loop, instead of expanding all commands, or, OTOH, complicated
4246 processing of output of "set".
4247 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4248 variable names in new macro...
4249 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4250 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4251 a loop to assign all ac_env_* and ac_cv_env_* variables.
4252 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4253 to INIT_PREPARE.
4254 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4255 its value to shell variable ac_precious_vars and call
4256 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4257 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4258 _AC_ARG_VAR_VALIDATE.
4260 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4261 and the AC_SUBSTs ...
4262 (AC_INIT): ... here.
4264 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4265 the ac_subst_files section in config.log.
4267 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
4269 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

4276 Fix problems reported by Nicolas Joly.
4277 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4278 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4279 They are generated by the Tru64 v5.1B shell.
4281 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4283 Fix my changes from 2005-07-01; reported by Noah Misch.
4284 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4285 description, the macro now accepts only a single tag.
4286 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4288 Fix cases when the varsions of Autoconf and Autotest don't match.
4289 Reported by Noah Misch.
4290 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4291 at_top_builddir, for compatibility with older autotest.
4292 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4293 is not set, use at_top_builddir, for compatibility with older
4294 versions of autoconf.
4296 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4298 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4299 Problem reported by Patrick Welche.
4301 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4303 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4304 sed substitution command, so that we allow | in program prefixes
4305 and program suffixes. (& is a problem anyway; we're not fixing
4306 that here.)
4307 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4308 configure_input, top_builddir, srcdir, etc.
4309 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4310 PATH_SEPARATOR in AUTOTEST_PATH.
4312 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4314 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4315 for loop over config.site files using `set', to allow
4316 directory names containing IFS characters.
4318 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
4320 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4321 directories with weird names. Apparently some people like living
4322 on the edge. However, improve the test that "pwd" actually does
4323 report a name for the working directory.

4339 (Generic Functions): Mention the Gnulib project.
4340 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4342 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4343 document to output the default config_* lists to config.status.
4344 Don't recognize option --file, if the functionality is not there.
4345 Likewise for --header; moreover, recognize --he and --h as shortcuts
4346 for --help in that case.
4348 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4349 matches the order of execution. No code changed.

4370 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4371 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4372 (AC_SUBST): Call it.
4373 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4374 the directory specific variables; but don't call it for configure_input.
4376 2005-06-28 Derek Price <derek@ximbiot.com>
4378 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4379 addition.
4381 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4383 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4384 directory have inherent problems with special characters like spaces,
4385 due to limitations in Make syntax. Problem reported by Alexandre
4386 Duret-Lutz.
4387 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4388 Also, fix Tru64 porting problem with shell patterns,

4400 from Justace Clutter.
4401 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4402 variable into diagnostic. Make the diagnostic an error, not a warning,
4403 because we really don't support spaces and suchlike in dir names.
4404 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4405 Don't worry about backslashes in srcdir; it can't happen now.
4406 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4407 Simplify ac_optarg handling.
4408 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4416 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4418 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4419 that '\|' is not allowed in BREs; recommend using newline separated
4420 list of patterns instead of multiple -e options.
4422 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4424 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4428 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
4430 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4432 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4433 b, t, r, w commands require single space, while : cannot have any.
4434 (Special Shell Variables): Fix sed code this in the example.
4435 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4436 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4438 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4439 expand to the empty list. Don't use two pairs of m4_changequote,
4440 it's not necessary.
4442 2005-06-20 Derek Price <derek@ximbiot.com>
4444 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4446 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4448 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4449 * doc/autoconf.texi:
4450 Don't mention Solaris versions so much, if a
4451 problem is common to all extant versions of Solaris. Say "SunOS
4452 4" instead of "SunOS" for SunOS 4.
4453 (awk): Mention more of the limitations of traditional Awk.
4454 (cat): Don't talk about cat -v.
4456 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4458 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4459 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4460 but the implementation is entirely different and is designed
4461 to be compatible with glibc strverscmp.
4462 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4464 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4465 on Mac OS X 10.4 reported by Peter O'Gorman in:
4466 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4467 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4468 Use shell builtins rather than 'expr', to work around expr bug.
4470 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4472 * doc/autoconf.texi: "filesystem" -> "file system".
4473 "behaviour" -> "behavior".
4474 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4475 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4476 as per POSIX.
4477 * lib/m4sugar/m4sh.m4: Likewise.

4479 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4481 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4482 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4483 to update the man page. That way, we don't have to check in new
4484 man pages every month.
4486 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4487 quotes and backslashes. Patch from Derek Price.
4489 2005-06-10 Derek Price <derek@ximbiot.com>
4491 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
4492 AS_TR_SH.
4494 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4496 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4497 -u, since it outputs chatter if the input files are the same.
4498 Problem reported by Ralf Menzel.
4500 2005-06-08 Derek Price <derek@ximbiot.com>
4502 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4503 renaming them since they are about to be redefined anyhow.
4505 2005-06-08 Derek Price <derek@ximbiot.com>
4507 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4508 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4509 Move m4_undefine to alphabetical order.
4511 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4513 * README: Recommend GNU M4 1.4.3 or later.
4514 * doc/autoconf.texi (Introduction): Likewise.
4515 Reword to avoid some formatting glitches.
4516 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4517 Clarify explanation of HP compiler bug.
4518 Redo example output tp match current CVS snapshot.
4519 Use @example.org in email addresses when the examples
4520 might get inadvertently cut-and-pasted into user code.
4521 Remove example of autom4te usage that doesn't seem to work now.
4522 Use modern AC_INIT (except when the example is meant to be
4523 shown with Autoconf 2.13).
4524 Update ksh info for Solaris 9 and later.
4525 KB -> kB.
4526 Modernize description of Automake versions a bit.
4527 Don't claim a future version of Autoconf is near.
4528 * doc/install.texi: Reword to avoid some formatting glitches.
4530 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4532 * doc/autoconf.texi: Add [] to examples, so that the manual
4533 follows its own advice about quoting better.
4534 Reword to avoid some formatting glitches.
4535 * doc/installt.exi: Reword to avoid some formatting glitches.
4537 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4538 Tru64 ksh pattern matching bug. Reported against Libtool by
4539 Albert Chin <libtool@mlists.thewrittenword.com> and
4540 Nicolas Joly <njoly@pasteur.fr>.
4542 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4544 m4_cdr of one-member list was [[]] (one-member list containing an
4545 empty string) instead of [] (an empty list. Callers were skewed to
4546 match this misbehaviour. As a consequence of this:
4547 - m4_foreach([x], [], [foo]) expanded to `foo', while
4548 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4549 This bug has been fixed:
4551 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4552 expand to an empty string; print error msg if called without
4553 an argument list.
4554 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4555 misbehaviour; handle [] and [[]] correctly.
4557 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4559 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4560 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4561 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4563 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4565 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4566 swallow records with more than 99 fields.
4567 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4568 parse the long line.
4570 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4572 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4573 swallow literals longer than 399. Reported by Ralf Wildenhues.
4574 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4575 to workaround this limitation.
4577 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4579 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4580 to gfortran, and make these the first two compiler names
4581 checked (following the general autoconf preference for gcc).
4583 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4585 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4586 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4587 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4589 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4591 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4592 expression of unbounded size when processing the --list
4593 option. This runs afoul of a limit of 399 bytes per regular
4594 expression on AIX. Problem reported by Ralf Wildenhues.
4596 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4598 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4599 * doc/autoconf.texi (Particular Headers): Reword example
4600 for multiline stdbool replacement.
4601 (Setting Output Variables): Reword text a bit. Don't
4602 give all the details about |#_!!_#|.
4603 Reword description of line replacement.
4605 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4607 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4608 now contain newlines, and substituted files must be referenced on
4609 a line alone; the sed scripts to substitute them are now very
4610 different.
4611 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4612 commands can be put in a sed script portably.
4613 * doc/autoconf.texi (Setting Output Variables): Document above
4614 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4615 use of multiline substitution.
4616 * tests/torture.at: No longer expect substitution of newline to fail.
4618 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4620 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4621 From Ralf Menzel (trivial change).
4623 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4625 * tests/local.at: Don't attempt to check for negated character
4626 classes in shell scripts. The test was too brittle.
4628 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4630 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4631 * doc/autoconf.texi (Limitations of Builtins): Document this
4632 limitation.
4634 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4636 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4637 common code; used in many places in the tree.
4638 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4639 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4641 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4643 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4644 messages when ac_unique_file is not found.
4645 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4646 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4647 commands, for consistency with AC_MSG_ERROR and such.
4649 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4651 * bin/Makefile.am: Merge the two rules for creating scripts.
4653 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4655 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4656 obsolete; it was never documented.
4657 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4659 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4661 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4662 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4663 (ac_top_builddir): ... this ...
4664 (ac_top_build_prefix): ... to this; the old name is also kept, for
4665 backward compatibility.
4666 (ac_top_builddir_sub): New variable, without the trailing slash,
4667 always nonempty.
4668 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4669 * doc/autoconf.texi (Configuration Actions): Rename
4670 ac_top_builddir to ac_top_build_prefix.
4671 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4672 at_top_builddir to at_top_build_prefix.
4673 * lib/autotest/general.m4 (AT_INIT): Likewise.
4675 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4677 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4678 of confdefs.h .
4680 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4682 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4683 argument to m4_foreach. I guess it was necessary in the past,
4684 but I think it's a no-op now.
4686 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4688 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4689 ``cat <<_ACEOF'' commands to one.
4690 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4691 * lib/autoconf/status.m4: On various places, use expr instead of
4692 ``echo|sed.''
4693 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4694 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4695 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4696 a range.
4697 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4698 the wrong patterns between ``case'' and ``esac.'' The previous
4699 code had false positives.
4701 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4703 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4704 as on 2005-05-02.
4705 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4706 Mention LIBOBJDIR.

4746 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4748 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4749 check.
4750 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4751 enough arguments, similarly as in m4_bpatsubsts.
4753 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4755 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4756 of absolute paths.
4758 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4760 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4761 for absolute directory names in one loop.
4762 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4763 abbreviations of --version and --debug.
4765 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4767 * doc/autoconf.texi (Autoconf Language): Be more precise about
4768 quoting rules. Problems noted by Stepan Kasal.
4769 Also, throughout this document, be more careful about white space.
4770 "blank", "white space", and "space" all have different meanings
4771 and we should be careful to say what we mean.
4773 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4775 Fix C++ related problems reported by Werner Lemberg.
4776 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4777 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4778 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4779 avoid problems with C++ and throw.
4780 * tests/compile.at: .cpp, not .cc.
4782 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4784 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4786 * doc/autoconf.texi (Generic Functions): Typos.
4788 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4790 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4791 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4792 set by latest automake.
4794 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4796 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4797 outputs 0 on GNU/Linux these days.
4799 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4801 * doc/autoconf.texi (Autoconf Language): Add more description
4802 about quoting heuristics.
4803 (Limitations of Builtins): Describe "set -" problems.
4805 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4807 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4808 not newline.
4810 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4811 by AC_DEFINE; it was a mistake.
4812 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4814 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4816 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4818 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4820 * doc/autoconf.texi (External Software): Quadrigraphs are not
4821 processed correctly in AS_HELP_STRING; avoid this in the examples.
4822 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4823 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4824 comment and reduce m4_default([foo], []) to [foo].
4825 (m4_strip): Update the explanation.
4827 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4829 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4830 Remove core.conftest.* too; it's generated by Tru64 5.1.
4831 Problem reported by Jennis Pruett.
4832 * lib/autoconf/functions.m4
4833 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4834 Don't bother to remove core files; AC_RUN_IFELSE should do that
4835 for you.
4837 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4839 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4841 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4843 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4844 Report from Horst Wente.
4846 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4848 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4849 the comment.
4851 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4853 * doc/autoconf.texi (External Software, Package Options): Add
4854 examples showing how to implement --with-* and --enable-* options.
4856 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4858 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4859 as well as configure.in. Problem reported by Gregorio Guidi.
4861 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4863 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4864 pattern for alloca snippet.

4874 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4876 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4877 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4879 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4881 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4882 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4883 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4884 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4885 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4887 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4889 * NEWS: The configure command now warns you if you attempt to use
4890 a directory whose name contains a special character like space,
4891 newline, or "\".
4892 * doc/autoconf.texi (Installation Directory Variables): Allow
4893 "," in file names. Do not use \@; it's not a portable regexp.
4894 * bin/Makefile.am (edit): Likewise.
4895 * lib/Makefile.am (edit): Likewise.
4896 * tests/Makefile.am (edit): Likewise.
4897 * tests/semantics.at: Likewise.
4898 * tests/torture.at: Likewise.
4899 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4900 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4901 * doc/autoconf.texi (File System Conventions): Warn about
4902 unportable file names.
4903 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4904 (AC_INIT): Use it.
4905 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4906 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4907 ac_pwd, and quote srcdir.
4908 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4910 * doc/autoconf.texi: Fix some systematic formatting problems.
4911 ".)" needs a following @: if not at the end of a sentence, and
4912 similarly for "!)". "etc." should be preceded by a comma.
4913 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4915 2005-03-22 Bruno Haible <bruno@clisp.org>
4917 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4918 argument is often called 'build-aux'.
4920 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4922 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4923 macro AC_TRY_LINK is obsolete.
4924 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4925 `AC_CONFIG_FILES'.
4927 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4929 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4930 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4931 from a Common Lisp's `cl'.
4932 (AC_PROG_CXX): Behave according to the documentation: don't
4933 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4934 make the variable CCC precious; use `cl.exe', not `cl'.
4936 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4937 Alexandre Duret-Lutz <adl@gnu.org>
4939 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4940 /dev/null, as "configure" shouldn't read stdin, and this insulates
4941 us from problems (e.g., when testing for "cl"). Also, do this
4942 redirection before invoking "hostname" or "uname", and keep the
4943 original input stream available via...
4944 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4945 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4946 bother with "</dev/null" since it's now done at the top of
4947 'configure'.
4948 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4949 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4950 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4951 * doc/autoconf.texi (File Descriptor Macros): New section.
4952 (Printing Messages): Mention it.
4953 * tests/base.at (Input/Output): New test.
4955 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4957 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4958 newline if neither \c nor -n work, as that would output two
4959 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4961 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4963 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4964 This causes that any required macros inside will get before the if.
4965 * doc/autoconf.texi (autom4te.cache): A typo.
4967 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4969 Undo previous change, except keep the change to
4970 lib/autoconf/programs.m4 that replaced grep with shell
4971 pattern-matching. This is because net-snmp configure reads stdin.
4972 Reported by Noah Misch.
4974 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4976 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4977 from /dev/null, as "configure" shouldn't read stdin, and this
4978 insulates us from problems (e.g., when testing for "cl").
4979 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4980 before invoking "hostname" or "uname".
4981 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4982 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4983 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4984 "</dev/null" since it's now done at the top of 'configure'.
4985 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4986 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4987 Also, replace grep with shell pattern-matching, to save a process.
4989 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4991 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4992 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4993 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4994 compiler.
4996 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4998 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4999 grep -q isn't portable. Improve grep -s explanation.
5000 Problem reported by Dan Manthey.
5002 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
5004 * doc/autoconf.texi (Special Shell Variables): Clarify
5005 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
5007 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
5009 * doc/autoconf.texi: Use @acronym for DJGPP.
5010 Fix some @code's that should have been @env's, and vice versa.
5011 Sort environment variable names.
5012 Mention that shells no longer inherit IFS.
5013 Don't recommend PATH_SEPARATOR=';' so strongly.
5014 Mention that $RANDOM might expand to the empty string.
5015 "symlink" and "soft link" -> "symbolic link".
5016 Improve mktemp description (reported by Bruno Haible).
5018 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>

5028 * NEWS: Mention AT_COPYRIGHT.
5030 * tests/local.at (AT_CMP): Use diff directly on input files rather
5031 than copying them.
5033 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5034 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

5037 and Paul Eggert <eggert@cs.ucla.edu>
5039 * tests/autotest.at (Empty test suite): New test.

5052 excess test name quoting.
5053 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5054 CPPFLAGS to `configure' instead of setting it in `configure'.
5056 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5057 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5058 on some platforms.
5060 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5061 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

5091 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5092 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5094 Try not to generated lines of unlimited length, as POSIX places a
5095 2047-byte limit on line length of portable text files.
5096 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5097 Use newline as a separator, not space.

5100 space.
5102 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5104 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5105 as_func_*. Add test to check whether positional parameters
5106 are restored after function return.
5108 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5110 * doc/autoconf.texi (Special Shell Variables): Mention _,
5111 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5112 if they contain a lower-case letter. The DUALCASE problem was
5113 reported by Ralf Wildenhues.
5115 * bin/autoconf.as: Don't exit with status 0 after write failure
5116 with --help or --version.
5117 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

5128 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
5130 * man/Makefile.am (.x.1): Go back to the simple solution, but take
5131 care to echo the commands, so the user knows what's going on.
5132 Modified from a suggestion by Stepan Kasal.
5134 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

5155 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5156 Update the long comment explaining it.
5158 m4_require no longer writes an ``is required by'' line to the
5159 execution stack. It contains only one bit of non-redundant
5160 information: that the macro was required, not called. And even
5161 this bit is useless in most situations: have you ever met a macro
5162 which both calls and requires the same macro?
5164 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5165 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5168 (m4_expansion_stack_pop): Remove the misplaced comment.
5169 (m4_require): Don't put the ``is required by'' line to the
5170 execution stack; slightly improve the out-of-a-defun error message.
5171 (_m4_divert_grow): New macro, counter for the temporary diversions.
5172 (_m4_require_call): Use it.
5173 * tests/m4sugar.at (m4_require): Expect output without the
5174 ``is required by'' messages.
5176 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5178 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5179 rather than x for expr.
5181 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5182 this is safe.
5183 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
5184 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

5196 from masters, so that FileUtils.pm's update_file provide --force
5197 support.
5198 * bin/autoheader.in: Pass $force to update_file so that
5199 config.h.in is always recreated when --force.

5203 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
5205 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5207 * doc/autoconf.texi (Limitations of Builtins): Clarify that
5208 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
5210 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5212 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5213 Warn about newline stripping in `` and $(). Update Solaris
5214 version to 9.
5215 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5216 X insulates us from future changes to Posix.
5217 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5218 stripping.
5220 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5238 ulongval to be static, to avoid unwanted GCC warning. Problem
5239 reported by Michael Jennings via Daniel Reed; see
5240 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
5242 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5244 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5249 new variables.
5251 2005-01-04 Noah Misch <noah@cs.caltech.edu>
5253 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
5254 not seem to work, assume it does set $(MAKE).

5265 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
5266 (_m4_divert_n_stack): New macro; the expansion is
5267 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5268 otherwise.
5269 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5270 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5271 stored in _m4_divert_diversion or _m4_divert_dump.
5272 (m4_divert_pop): When the parameter is given, compare the symbolic
5273 name with the last diversion pushed on the stack. Previously, the
5274 current diversion was compared with the numeric value of the
5275 diversion given as the parameter.
5276 (m4_require): If the macro hasn't been expanded yet, call ...
5277 (_m4_require_call): this new macro.
5279 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

5310 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5312 not essential. Reported by Magnus Therning.
5313 * tests/torture.at (autoreconf.): New banner.
5314 (autoreconf and non-AC configure): Rename to `Non-Autoconf
5315 AC_CONFIG_SUBDIRS'.

5363 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5364 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5442 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
5443 generated conftest files.

5491 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
5492 Don't depend on .x file explicitly, since "make" does that for us.
5493 Suggested by Stepan Kasal.
5495 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
5496 Add *.tmp.
5497 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

5556 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5558 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5559 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5560 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

5580 with exactly one parameter.
5582 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5584 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5585 "char c = '\200';" rather than "char c = 0x80;" as the
5586 latter doesn't conform to the strict C standard due to
5587 overflow on signed char hosts.
5589 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5590 to -qlanglvl=ansi. We don't want to disable extensions.
5592 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5594 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.

5650 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5651 the $1_found variable, don't test whether the file is executable;

5664 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
5665 limitations. Reorder paragraphs for clarity.

5669 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

5690 Problem reported by Stepan Kasal.
5692 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5694 Fix problems reported by Andreas Buening in:

5701 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5703 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5704 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5705 (trivial change). Problem and patch reported by Andrew Church in:
5706 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5708 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

5713 Also, fix some minor spacing and punctuation bugs.
5715 2004-09-02 Akim Demaille <akim@epita.fr>
5717 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

5735 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5736 texinfo.tex for now (done by hand now).

5738 Remove ansi2knr.c; nobody uses it.
5739 (ansi2knr.c-url_prefix): Remove.
5740 (cvs-update): Fix test for failure. I don't know why it ever
5741 worked...
5743 * doc/autoconf.texi: Update URLs, some of which went stale.
5744 Use @uref rather than @href.
5746 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5747 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5749 * config/config.guess, config/config.sub, config/elisp-comp,
5750 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5751 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5753 * NEWS, TODO, configure.ac, bin/autoscan.in,
5754 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5755 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5759 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5760 tests/tools.at, tests/torture.at:
5761 Use "file name" rather than "filename" or "path",
5762 to be consistent with the terminology of the GNU coding standards.
5764 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5766 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5767 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with

5771 More fixes to support spaces in the name of the build directory.
5772 This isn't a complete fix but it's an improvement.
5774 * bin/autoconf.as (autom4te_options): New var.
5775 Use it instead of appending to AUTOM4TE, so that we can allow
5776 spaces in the build directory's absolute name.
5777 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5778 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5797 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5799 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5800 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5801 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5803 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5805 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5806 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5807 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5808 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5809 * lib/autom4te.in (Automake-preselections): Preselect
5810 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5812 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5814 * lib/autom4te.in (Automake-preselections): Preselect
5815 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5816 trace them.
5818 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5820 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5821 Tru64.

5827 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5828 with pdksh, too. Problem reported by Patrick Welche via
5829 Gary V. Vaughan.
5830 * doc/autoconf.texi (Shellology): Note that set -o posix is
5831 useful for pkdsh, too.
5833 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5835 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5836 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5837 Don't fail if ENV or BASH_ENV is readonly.
5838 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5839 etc. are read only. Problem reported by Ludovic Courtes.
5841 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5843 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

5847 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5849 * doc/autoconf.texi (File System Conventions): Warn about
5850 names like "aux". Problem reported by Eric Blake.
5852 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5853 by zero instead of array size, so that we can use any arithmetic
5854 constant expression (instead of requiring an integer constant
5855 expression). This allows us to test expressions like DBL_MAX <
5856 LDBL_MAX, which didn't conform to the C standard using the old
5857 method.
5858 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5859 now that we can do floating-point tests at compile time.
5861 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5863 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5864 and LDBL_EPSILON, as the resulting expression isn't an
5865 integer constant expression and violates the C standard.
5866 Problem reported by Nelson H. F. Beebe. Also, check
5867 for "L" suffix, and check that long double doesn't have
5868 worse range or precision than double, that mixed-mode
5869 arithmetic doesn't generate a diagnostic, that double
5870 constants fit in long double.
5872 2004-06-03 Kevin Ryde <user42@zip.com.au>
5874 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5875 malloc(0) and realloc(NULL,size).
5877 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5878 Bob Proulx.
5880 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5882 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5883 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5884 by Jim Meyering.
5886 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5888 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5889 can be rewritten using if-then-else. Suggested by Bruno Haible.
5891 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5893 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5894 Problem reported by Stepan Kasal.
5896 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5898 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5899 change). Patch reported by Ralf Wildenhues in
5900 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5902 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5903 function F exists if the compiler and linker let you compile an
5904 expression like (F != 0). Recent versions of GCC optimize away
5905 the reference to F in that case, since every function address must
5906 be nonzero, so the link succeeds even if F does not exist.
5907 Problem reported by Manu in
5908 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5910 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5911 "Unix". Many uses changed.
5912 (Limitations of Builtins): Explain better why the ! command isn't
5913 portable.
5915 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5917 * lib/autom4te.in (Automake-preselections): Preselect
5918 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5920 2004-05-19 Kevin Ryde <user42@zip.com.au>
5922 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5923 referencing AC_FUNC_STRERROR_R.
5925 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5926 note pessimistic assumption when cross compiling.
5928 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5930 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5931 (until 2004) invoked subcommands with sh -e, contra POSIX.
5932 Reported by Kevin Ryde.
5934 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5936 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5937 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5938 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5939 `test -f " /usr/bin/grep"', which _always_ failed.
5940 (AC_PROG_SED): Ditto bogus PATH fix.
5941 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5942 requires that grep correctly supports _multiple_ `-e' options, rather
5943 than stating only that grep should accept `-e'.
5945 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5947 Port to C99, which requires that 'exit' be declared.
5949 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5950 to ensure that stdlib.h is included.
5951 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5952 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5953 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5954 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5955 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5956 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5957 when using 'exit' in a test; C99 requires that 'exit' be declared.
5959 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5961 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5962 now prefers 'grep' implementations that accept -e.
5963 (Limitations of Usual Tools): Describe problems of traditional
5964 egrep and fgrep with long input lines, and of traditional grep
5965 with -e.
5966 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5967 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5968 All callers changed. Append /usr/xpg4/bin to the PATH, for
5969 Solaris.
5970 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5971 the user with complaints about multiple -e options.
5972 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5973 Define it with AC_PROG_GREP.
5974 * configure.ac (AC_PROG_GREP): Add.
5975 * lib/freeze.mk (GREP): New macro.
5977 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5979 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5980 a possible candidate only after all others fail, rather than
5981 consulting it first. This improves backward compatibility by
5982 better reflecting the way shell selection occurred in previous
5983 versions of Autoconf, and should help to avoid triggering latent
5984 problems in other packages, such as the one in Automake where zsh
5985 is not handled robustly:
5986 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5987 Although it is not Autoconf's responsibility to work around
5988 problems in Automake, it nevertheless makes sense to avoid
5989 introducing unnecessary incompatibilites.
5991 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5992 Gary V. Vaughan <gary@gnu.org>
5994 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5995 how deeply nested we are when a suitable tool is found, set the
5996 ac_path_TOOL_found flag.
5997 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5998 nested we are in this macro. Break out of all 3 nested loops if
5999 ac_path_TOOL_found is set.
6001 2004-04-21 Gary V. Vaughan <gary@gnu.org>
6003 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
6004 of the _AS_PATH_WALK loop too if GNU flavor is found.
6006 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
6008 * doc/autoconf.texi (Limitations of Make): Update documentation
6009 for `$<'. New entry `Long lines', based on a report from Simon
6010 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6011 paragraph about DJGPP, based on a mail from Richard Dawe.
6013 2004-04-20 Paul Eggert <eggert@twinsun.com>
6015 * tests/c.at (C keywords): Don't assume that GCC supports
6016 "restrict" and "inline", as sufficiently-old GCC versions do not
6017 (also, GCC configured to be in pedantic C89 mode does not).
6018 Problem reported by Sumit Pandya in:
6019 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6021 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6022 consider -g to work if it generates warnings when plain compiles
6023 don't. Problem reported by Braden McDaniel in:
6024 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6026 * doc/autoconf.texi (Slashes): New section, to document a problem
6027 reported by Jim Meyering in:
6028 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6030 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6031 linker output files before linking, to work around IRIX 6 linker bug.
6032 Problem reported by Rainer Orth in:
6033 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6035 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6037 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6038 best tool so far counter rely on the tool path variable name to
6039 avoid checks for one tool being affected by the results of running
6040 the length check on a previous tool.
6042 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
6043 match expression argument, as different greps have different
6044 regular expression flavours.
6045 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
6046 literals.
6047 (AC_PROG_EGREP): Pass 'EGREP$'.
6048 (AC_PROG_GREP): Pass 'GREP$'.
6050 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6052 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6053 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6055 2004-03-29 Paul Eggert <eggert@twinsun.com>
6057 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6058 Types, Specific Compiler Characteristics, System Services,
6059 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6060 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6061 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6062 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6063 Likewise.
6064 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6065 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6066 AC_TYPE_OFF_T): Likewise.
6067 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6068 Likewise.
6070 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6071 pacify libtool 1.5.2. Fix quoting problems in sed command.
6073 2004-03-28 Paul Eggert <eggert@twinsun.com>
6075 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6076 now defines HAVE_DECL_TZNAME if it is declared, when
6077 HAVE_STRUCT_TM_TM_ZONE is not defined.
6078 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6079 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6080 for HAVE_TZNAME.
6082 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6084 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6085 superfluous backslashing of quotes (") in sed expressions;
6086 thanks to Paul Eggert.
6088 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6090 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6091 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6092 H. F. Beebe for the bug report.
6094 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6096 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6097 quoted -cmdline argument in Portland Group compiler (bug
6098 reported by Jeffrey J. Barteet).
6100 2004-03-25 Kevin Ryde <user42@zip.com.au>
6102 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to

6124 AC_CHECK_TOOLS.
6125 (Specifying Names): Document the reason for these future
6126 behavioral changes.

6128 new macros.
6129 * NEWS: Document these changes.
6131 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6132 they make TeX hang up.

6137 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6138 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6139 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6140 vowel.
6141 (AC_CHECK_ALIGNOF): New macro.
6142 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6143 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6144 those for sizeof.
6146 2004-03-03 Paul Eggert <eggert@twinsun.com>
6148 * bin/Makefile.am (edit): Don't use $< in a context where
6149 POSIX doesn't require support for it. Use $@.in instead.
6150 Problem reported by Anthony N. Frasso in
6151 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6152 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.

6182 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6183 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6184 Darwin uses -lcrt2.o and there's little point to cataloging all
6185 the system variants. Partial fix reported by Andreas Waechter in:
6186 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

6200 refer to the correct file.
6201 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6202 the behavior of the third argument.
6203 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6204 correctly the behavior of the third argument. Document

6310 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6311 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6312 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6313 not <inttypes.h>. Problem reported by Tim Mooney in
6314 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6315 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6316 Likewise.
6318 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6319 otherwise "make check" fails because it forbids cmp (I guess
6320 because cmp treats files as binary on DOS-like systems).
6322 * tests/mktests.sh: Update copyright date to 2004, since some tests
6323 have changed in 2004.
6325 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6327 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6328 non-truncating sed or gsed program in PATH.
6329 * tests/acprograms.at: Add it.
6330 * doc/autoconf.texi (Particular Programs): Document it.
6331 * NEWS: Updated.
6333 2004-01-15 Paul Eggert <eggert@twinsun.com>
6335 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6336 -std1 disables some useful extensions on Tru64. Problem reported
6337 by N. Lichtmaier in
6338 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6340 2004-01-14 Paul Eggert <eggert@twinsun.com>
6342 * doc/autoconf.texi (Programming in M4sh): Document that
6343 AS_MKDIR_P succeeds if the destination is a symbolic link
6344 to an existing directory.
6345 (Limitations of Usual Tools): Note that mkdir -p might not
6346 succeed on symlinks to directories.
6348 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6350 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6351 * bin/autoheader.in: Grammar fix in message.
6352 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

6358 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6360 2004-01-10 Jim Meyering <jim@meyering.net>
6362 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
6364 2004-01-09 Paul Eggert <eggert@twinsun.com>
6366 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6367 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6368 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6369 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6370 AC_COMPILE_IFELSE, since we now assume our caller invokes
6371 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6372 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6373 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6374 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6376 2004-01-07 Paul Eggert <eggert@twinsun.com>
6378 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6379 `"'...'"`, as it's confusing (and I suspect it may not work on
6380 some platforms). The code was incorrect anyway, as it assumed
6381 that \$ evaluated to itself in that context. Reported by
6382 Alexandre Duret-Lutz.
6384 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6386 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

6392 example, and add more examples. Reported by Eric Sunshine.
6394 2004-01-05 Paul Eggert <eggert@twinsun.com>
6396 * doc/autoconf.texi (Limitations of Usual Tools):
6397 Remove warning against "rm -fr" introduced yesterday; it
6398 was a false alarm.
6400 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6401 autoscan, autoupdate, ifnames): Don't use chmod -w.
6402 * lib/Makefile.am (autom4te.cfg): Likewise.
6403 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6404 "chmod -w".

6409 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6410 by doing lineno substitution only on lines containing "$LINENO".
6412 2004-01-04 Paul Eggert <eggert@twinsun.com>
6414 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6415 Use "rm -f" to remove conftest.sed, not plain "rm".
6416 Bug reported by David Relson in
6417 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6419 * Makefile.am (autom4te-update):
6420 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6421 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6422 * doc/autoconf.texi (Guidelines): Likewise.
6423 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6428 * tests/Makefile.am (clean-local): Likewise.
6429 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6430 srcdir): Likewise.
6431 * doc/autoconf.texi (Limitations of Usual Tools):
6432 Warn against "rm -fr".
6434 2004-01-03 Paul Eggert <eggert@twinsun.com>
6436 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6437 -c -o might not work. From a suggestion by Kevin Ryde.
6438 (C Compiler, Generating Sources, Limitations
6439 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6440 Don't put '-o' after non-options, as POSIX doesn't allow this.
6441 Mention that cc's name might be gcc or c89 or whatever.
6443 2004-01-04 Kevin Ryde <user42@zip.com.au>
6445 * doc/autoconf.texi: Add various further index entries.
6447 2003-12-29 Paul Eggert <eggert@twinsun.com>
6449 * bin/autoreconf.in (autoreconf_current_directory):
6450 Fix typo: mkdir without umask arg.
6452 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6454 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6455 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6456 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6457 explanation clearer.
6459 2003-12-24 Andreas Schwab <schwab@suse.de>
6461 * doc/autoconf.texi (Default Includes): Fix misspelling of

6466 * configure.ac: Test if sh -n works.
6467 * configure: Regenerate.
6468 * tests/atlocal.in: Store the result here.
6469 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

6471 of explicitly testing.
6472 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6473 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6474 * tests/tools.at (Syntax of the shell scripts): Simplify
6475 using AT_CHECK_SHELL_SYNTAX.

6491 macros.
6492 (AS_SHELL_SANITIZE): Move reinvocation code from
6493 _AS_LINENO_WORKS, use it to find out if shell
6494 functions work.
6495 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6496 does not work.
6497 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6498 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6509 (&sizes): New.
6510 Use them.

6512 them on the fly.
6514 2003-11-24 Akim Demaille <akim@epita.fr>
6516 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6557 2003-11-15 Kevin Ryde <user42@zip.com.au>
6559 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6560 than $target since the latter is not usual, add guidelines on when to

6565 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a

6585 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

6742 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6743 -mGLOB_options_string stuff for Intel ifc, which can cause
6744 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6745 pattern-matching instead of grep.
6747 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>

6767 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6768 cache variable instead of $G77 to decide whether to include -O2,
6769 since $G77 is specific to Fortran 77.
6771 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6773 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f

6781 remove/deprecate the DIALECT optional argument in the future if it
6782 proves troublesome.
6783 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6784 non-freeform-supporting compilers. Document freeform flags.

6791 2003-10-03 Akim Demaille <akim@epita.fr>
6793 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6794 * bin/autoreconf.in (autoreconf_current_directory): Create the
6795 AUX_DIR if needed, for sake of automake --add-missing etc.
6796 Suggested by Alexandre Duret-Lutz.
6798 2003-10-03 Akim Demaille <akim@epita.fr>
6800 * configure.ac: Quotation and formatting changes.
6801 (EMACS): Don't set it if it is not recent enough to support
6802 autoconf-mode.el.
6803 From Eric Sunshine.
6805 2003-10-02 Akim Demaille <akim@epita.fr>
6807 * bin/ifnames.in (&scan_file): Skip C++ comments.

6819 2003-09-30 Paul Eggert <eggert@twinsun.com>
6821 * lib/Autom4te/XFile.pm: Use Errno.
6822 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6823 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6825 2003-09-30 Akim Demaille <akim@epita.fr>
6827 * config/announce-gen (&print_news_deltas): Extracted from...
6828 (&print_changelog_deltas): here.
6829 (&news_file): Rename as...
6830 (@news_file): this.

6834 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6835 have been created when invoking the compiler.

6846 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6847 Problem reported by Lars J. Aas in
6848 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6849 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6850 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6851 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6853 2003-09-26 Akim Demaille <akim@epita.fr>
6855 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6856 directory for AC_CONFIG_COMMANDS' first argument exists.
6857 This makes valid the invocation of _AC_SRCPATH that follows.
6858 Reported by Eric Sunshine.
6859 * doc/autoconf.texi (Configuration Commands): Adjust.
6861 2003-09-26 Akim Demaille <akim@epita.fr>
6863 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6864 Reported by Ralf Corsepius.
6866 2003-09-26 Akim Demaille <akim@epita.fr>
6868 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6869 arguments.
6870 Actually, use AU_ALIAS.
6871 From Bruno Haible.
6873 2003-09-26 Paul Eggert <eggert@twinsun.com>
6875 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6876 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6877 Problem reported by Eric Sunshine in:

6880 2003-09-26 Akim Demaille <akim@epita.fr>
6882 The test suite are sometimes assigning timings incorrectly.
6883 Reported by Henk Krus.
6884 Diagnosed by Nicolas Joly.
6886 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6887 AT_help_all.
6888 Instead of making AT_help a sequence of assignments to grow
6889 $at_help_all, just make AT_help_all be the growing contents of
6890 $at_help_all, and make a single assignment in...
6891 (AT_INIT): here.
6892 (at_times_skip): Flip the meaning and rename as...
6893 (at_times_p): this.
6894 (AT_INIT): When summarizing the test that ran, remove
6895 $at_times_file after use, and check it is present before trying to
6896 use it.
6898 2003-09-25 Akim Demaille <akim@epita.fr>
6900 Version 2.57d.
6902 * bin/Makefile.am (edit): Handle '@configure_input@'.
6903 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6904 (ifnames): chmod -w.
6905 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6906 executables, not bin/ executables! Otherwise all the magic needed
6907 to find non installed files is turned off. This caused a failure
6908 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6909 as found in its environment (sent by tests/autoreconf): pointing
6910 to bin/autom4te that could not find its files.
6911 * tests/mktests.sh: Force the replacement of generated files, for
6912 the sake of "mv" program that are interactive when overwriting a
6913 -w file.
6914 * config/install-sh: Upgrade from CVS Automake.
6916 2003-09-23 Paul Eggert <eggert@twinsun.com>
6918 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6919 versus test -L issues.
6921 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6922 Paul Eggert <eggert@twinsun.com>
6924 Trivial change to support GCC's configuration procedure.
6925 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6926 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6927 about inconsistency if the preprocessor is set to give errors for
6928 any warning.
6929 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6931 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6933 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm

6947 2003-09-12 Akim Demaille <akim@epita.fr>
6949 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6950 not asm/types.h.

6954 * doc/autoconf.texi (Header Portability): linux/random.h.
6955 From Peter Hendrickson.
6957 2003-09-10 Akim Demaille <akim@epita.fr>
6959 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6960 willing to edit the output files.
6962 2003-09-10 Akim Demaille <akim@epita.fr>
6964 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6965 and AC_FC_FREEFORM.
6966 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6967 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6969 2003-09-09 Akim Demaille <akim@epita.fr>
6971 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6972 Reported by Gary Vaughan.

6978 trailing files.
6980 2003-09-07 Paul Eggert <eggert@twinsun.com>
6982 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6983 Improve the accuracy of the wording about obsolescence.
6984 From a suggestion by Ian Lance Taylor in
6985 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6987 2003-09-05 Paul Eggert <eggert@twinsun.com>
6989 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6990 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6992 2003-09-04 Akim Demaille <akim@epita.fr>
6994 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6995 AC_FUNC_WAIT3.
6997 2003-09-04 Akim Demaille <akim@epita.fr>
6999 * bin/autom4te.in: Use &fatal where more appropriate than &error.
7000 (freeze): When exiting, use $exit_code.
7001 * lib/autoconf/fortran.m4: Comment changes.
7003 2003-09-04 Akim Demaille <akim@epita.fr>
7005 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
7007 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
7009 Add support for newer Fortran dialects. The F77 interface is
7010 unchanged, and continues to support Fortran 77. New FC macros
7011 correspond to all the old F77 macros, with output variables FC,
7012 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7013 available dialect, but older dialects can be specified. There are
7014 new macros AC_FC_SRCEXT to set the source extension, and
7015 AC_FC_FREEFORM to accept free-form source files.
7017 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
7018 New macros.
7019 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

7035 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
7036 Rewrite in terms of the above.
7037 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
7038 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
7039 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
7040 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

7044 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
7045 Document problems with timestamp resolution that 'make', 'cp -p', and
7046 'touch -r' have.
7048 2003-08-27 Akim Demaille <akim@epita.fr>
7050 * tests/m4sugar.at (cross_warning): Make sure to enable the
7051 output, so that we can track spurious m4sugar output.
7052 * tests/local.at: Require 2.57.
7053 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7054 are defaulted by AT_CHECK anyway.
7055 Use AT_CHECK_AUTOM4TE.
7056 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7057 missing dnl.
7059 2003-08-27 Akim Demaille <akim@epita.fr>
7061 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7062 when -Wobsolete is set.
7063 Set it on by default.
7064 Suggested by Klee Dienes.
7066 2003-08-27 Akim Demaille <akim@epita.fr>

7115 * bin/autom4te.in: Adjust to output the call stack.
7116 * tests/m4sugar.at (m4@&t@_warn): Adjust.
7118 2003-08-22 Akim Demaille <akim@epita.fr>
7120 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
7121 * bin/autom4te.in: Adjust.

7125 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
7126 (&verbose): Remove.
7127 (&getopt): Adjust the note and verb channels, depending upon
7128 --verbose.

7141 2003-08-21 Akim Demaille <akim@epita.fr>
7143 First stab at preserving warnings between calls to autom4te,
7144 including when the cache is used.
7146 There are still several issues: (i) there are too many runs of m4
7147 (one for include, one for warnings, and some more), (ii) warnings
7148 spreading on several lines are not handled gracefully, (iii) the
7149 code meant to have the call stack display for errors does not work
7150 (its handling should move from m4 to autom4te).
7152 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7153 Use them.
7154 (@preselect): Add m4_warn.
7155 ($exit_status): Remove, use $exit_code.
7156 ($help): Use Autom4te::ChannelDefs::usage.
7157 (&handle_m4): No longer define the m4_warnings.
7158 At each run, extract and report the warnings.
7159 Always cache the result, including if the exit status is on
7160 failure, since if nothing changes, we should result in the same
7161 failure, hence we can use the cache.
7162 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7163 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7164 Remove.
7165 (m4_warn): Redefine as a do-nothing: it is its invocation that
7166 matters, as warnings are now reported via traces.
7167 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7168 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7169 the latter reveals calls to the former.
7171 Adjust the tests.
7173 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7175 2003-08-21 Akim Demaille <akim@epita.fr>
7177 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7178 Use them.
7180 2003-08-21 Akim Demaille <akim@epita.fr>
7182 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7183 forward order.
7184 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7185 (&parse_warnings): Accept a list of warning requests.
7186 (&usage): Return a string, not a side effect.
7187 (cross): New warning category.
7189 2003-08-21 Akim Demaille <akim@epita.fr>
7191 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7192 (&require_configure_ac): Accept an optional directory argument.
7193 ($configure_ac): Remove.
7194 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7195 (&catfile): Remove.
7196 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7197 * bin/autoscan.in: Adjust.
7199 2003-08-20 Akim Demaille <akim@epita.fr>
7201 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7202 Reported by Alexandre Duret-Lutz.
7204 2003-08-20 Akim Demaille <akim@epita.fr>
7206 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7207 * bin/autom4te: Adjust.
7208 In particular, be Autoconf tools are really silent when properly
7209 working, bind the verbosity of the 'note' channel to $verbose.
7210 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7211 (&xsystem, &contents): Remove, since they are exported by...
7212 * lib/Autom4te/FileUtils.pm: this.
7213 More perldoc.
7214 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7215 * lib/Autom4te/FileUtils.pm: here.
7217 2003-08-20 Akim Demaille <akim@epita.fr>
7219 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7220 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7247 and m4_sinclude.
7249 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
7251 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...
7252 (Autoconf-without-aclocal-m4): ... this new language.
7253 * doc/autoconf.texi (autom4te Invocation): Mention
7254 Autoconf-without-aclocal-m4.
7256 2003-08-18 Derek Price <derek@ximbiot.com>
7258 * doc/autoconf.texi (Writing testsuite.at): Document RUN-IF-FAIL &
7259 RUN-IF-PASS optional arguments.

7270 2003-08-14 Derek Price <derek@ximbiot.com>
7272 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7273 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7274 shorter column three. Add DESCRIPTION to log file content.
7276 2003-08-13 Derek Price <derek@ximbiot.com>
7278 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7279 output.
7281 2003-08-12 Derek Price <derek@ximbiot.com>
7283 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
7284 (AT_CHECK_NOESCAPE): Move core functionality to...
7285 (_AT_CHECK): ...this new macro.
7287 2003-08-07 Derek Price <derek@ximbiot.com>
7289 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
7290 (AT_CHECK_NOESCAPE): ...to this new macro.
7292 2003-07-31 Paul Eggert <eggert@twinsun.com>
7294 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
7295 in Bash 2.01. Problem reported by Brian Gough in
7296 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
7298 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
7300 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
7301 -lcrt1.o, for OS X. (trivial change)
7303 2003-07-07 Paul Eggert <eggert@twinsun.com>
7305 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
7306 inside '#ifndef __cplusplus'. Problem reported by
7307 Bob Friesenhahn.
7309 2003-07-06 Bill Clarke <llib@computer.org>
7311 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
7312 'long', not 'int', for benefit of Sun's recent C++ compilers
7313 (trivial change). See:
7314 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
7315 (This really should be 'intptr_t', not 'long', but that would
7316 take more work.)
7318 2003-06-25 Akim Demaille <akim@epita.fr>
7320 * lib/Makefile.am (autom4te.cfg): Make it read only.
7321 Depend on Makefile since it contains substitutions.
7322 From Paolo Bonzini.
7323 * lib/autom4te.in (args): Add local.at? for Autotest args.
7324 This change was made on autom4te.cfg which is generated.
7325 Reported by Raja R. Harinath.
7327 2003-06-25 Akim Demaille <akim@epita.fr>
7329 * doc/autoconf.texi (Header Portability): sys/mount.h.
7330 From Gareth McCaughan.
7332 2003-06-23 Akim Demaille <akim@epita.fr>
7334 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7335 not all of them. This fixes 1. the fact that when testing
7336 Autoconf there are many many config.log, 2. the incorrect use of
7337 top_srcdir to find config.log.
7338 Don't mix the detailed output of failed test with the summary of
7339 failures. Rather, append detailed log afterwards.
7341 2003-06-23 Akim Demaille <akim@epita.fr>
7343 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7344 always run: output config.log on $at_group_log.
7346 2003-06-23 Akim Demaille <akim@epita.fr>
7348 * tests/torture.at (#define header templates): Don't use quotes in
7349 C++ comments as it puzzles Emacs' sh font-lock-mode.
7351 2003-06-23 Akim Demaille <akim@epita.fr>
7353 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7354 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7355 * tests/atspecific.m4: Rename as...
7356 * tests/local.at: This.
7357 * tests/suite.at: Move the globals into...
7358 * tests/local.at: here.
7359 * tests/Makefile.am: Adjust.
7360 * doc/autoconf.texi (testsuite Scripts): Adjust.
7362 2003-06-21 Kevin Ryde <user42@zip.com.au>
7364 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7365 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7366 ensuring we add -std1 for full-ANSI.
7368 * doc/autoconf.texi (hdrindex): New macro.
7369 Add index entries for portability of various standard header files.
7371 2003-06-20 Akim Demaille <akim@epita.fr>
7373 * configure.ac: Bump to 2.57b.
7375 2003-06-20 Akim Demaille <akim@epita.fr>
7377 Version 2.57a.
7379 2003-06-20 Akim Demaille <akim@epita.fr>
7381 * bin/autom4te.in: Don't rely on $HOME being defined.
7382 Reported by Marc Espie as PR/233.
7384 2003-06-20 Akim Demaille <akim@epita.fr>
7386 * lib/autotest/general.m4: Use at_times_file only if used.
7387 From Nicolas Joly.
7389 2003-06-20 Akim Demaille <akim@epita.fr>
7391 * config/config.guess, config/config.sub, config/elisp-comp,
7392 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7393 Update from masters.
7395 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7397 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7398 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7399 (TEST_SCRIPT): New diversion.
7400 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7401 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7402 (AT_INIT): Support for expected failures.
7404 2003-06-02 Akim Demaille <akim@epita.fr>
7406 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7407 changes.
7408 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7409 Autoconf nor Automake.
7410 (&contents): New, from Automake.
7411 PODify.
7413 2003-05-28 Paul Eggert <eggert@twinsun.com>
7415 * NEWS, doc/autoconf.texi (Particular Functions),
7416 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7417 is the inverse of localtime.
7419 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7421 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7422 (handle_exec_errors): New function. Work around $! being
7423 altered by WEXITSTATUS.
7424 (xqx, xsystem): Use handle_exec_errors.
7426 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7428 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7429 Do not call `_exit()', simply modify `$?'.
7430 (xsystem): Reset $! before running system, and check it afterward.
7431 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7432 63 for version mismatches.
7434 2003-05-23 Akim Demaille <akim@epita.fr>
7436 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7437 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7438 the middle of a line).
7439 * lib/m4sugar/m4sugar.m4: Likewise.
7440 Remove useless spaces in comments.
7442 2003-05-23 Akim Demaille <akim@epita.fr>
7444 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7445 exit 63, so that we (or Automake's "missing") can tell the
7446 difference with a plain failure.
7447 * doc/autoconf.texi (Notices): Adjust.
7449 2003-05-23 Akim Demaille <akim@epita.fr>
7451 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7452 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7453 White spaces cleanup.
7455 2003-05-22 Jim Meyering <jim@meyering.net>
7456 Paul Eggert <eggert@twinsun.com>
7458 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7459 Remove `#include <stdlib.h>' from the list; we should never
7460 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7461 resulting namespace pollution would cause other tests to fail.
7462 Configure scripts run with some older versions of g++ and HP's
7463 aCC would fail due to such an #include. Problems reported by
7464 Matthew Mueller in <http://bugs.debian.org/120704> and by
7465 Keith Bostic in
7466 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7467 In the test, use the test declaration before including <stdlib.h>,
7468 as that's closer to how it'll be used.
7470 2003-05-23 Akim Demaille <akim@epita.fr>
7472 * doc/autoconf.texi (Header Portability): ucred.h.
7473 From Ian Redfern.
7475 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7477 Overhaul Autotest's logging: generate separate log files
7478 in testsuite.dir/NNN/testsuite.log, and append them to
7479 testsuite.log instead of re-running the test verbosely.
7481 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7482 file descriptor, write 0 to at_status_file instead of setting
7483 at_status=0, initialize some new variables (at_status_file,
7484 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7485 to rerun the tests, instead append the at_group_log to the
7486 at_suite_log when a test fails.
7487 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7488 with the AS_MESSAGE_LOG_FD redirected to stdout.
7489 (AT_CLEANUP): save the output status in $at_status_file
7490 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7491 its original place.
7492 (AT_CHECK): since tests are run with a redirected stdout,
7493 and used to be re-run in verbose mode, turn some $at_verbose
7494 into echo, and don't redirect the output of testing stdout
7495 and stderr.
7497 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7498 the name of the debugging directory and information about
7499 its contents.
7501 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7503 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7504 parameter.
7506 2003-05-22 Akim Demaille <akim@epita.fr>
7508 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
7509 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
7510 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4
7511 * lib/autoconf/status.m4: Fix and adjust copyright notices.
7513 2003-05-22 Akim Demaille <akim@epita.fr>

7526 Whitespace clean up.
7527 Suggested by Jim Meyering.
7529 2003-05-22 Akim Demaille <akim@epita.fr>
7531 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7532 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7533 Reported by Jim Meyering.
7535 2003-05-22 Akim Demaille <akim@epita.fr>
7537 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7552 it to eval.
7554 2003-05-21 Akim Demaille <akim@epita.fr>
7556 * bin/autoupdate.in ($m4): Fix quotation.

7568 AC_CHECK_HEADERS_NEW): New tests.
7570 2003-05-17 Akim Demaille <akim@epita.fr>
7572 * lib/autoconf/functions.m4: Use the default includes so that
7573 memcmp be declared before being tested.
7574 Reported by Sander Niemeijer.
7575 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7576 * doc/autoconf.texi (Default Includes): Document
7577 AC_INCLUDES_DEFAULT.
7579 2003-05-17 Akim Demaille <akim@epita.fr>
7581 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7582 * doc/autoconf.texi (Obsolete Macros): Adjust.
7583 Reported by Werner LEMBERG and Debian Bug 190886.
7585 2003-05-16 Akim Demaille <akim@epita.fr>
7587 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7588 user name space clashes.
7589 Reported by Bruno Haible.
7591 2003-05-16 Akim Demaille <akim@epita.fr>
7593 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7594 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7595 them uniform, and more robust to Perl special characters.
7596 Reported by Martin Mokrejs.
7598 2003-05-14 Akim Demaille <akim@epita.fr>
7600 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7602 2003-05-14 Akim Demaille <akim@epita.fr>
7604 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,
7605 linux/irda.h.

7609 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7610 message.
7611 From Matthias Andree.
7613 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>

7616 and truncate.
7618 2003-05-06 Akim Demaille <akim@epita.fr>
7620 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7621 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7622 by aclocal.m4 is changed it might require the importing of another
7623 m4 extension file, i.e., aclocal must be run.
7625 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7626 (&parse_args): Use --force with aclocal if required and supported.
7627 (&autoreconf_current_directory): Use &run_aclocal.

7631 Lock autom4te's cache.
7633 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7634 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7635 argument instead of a file name, so that the request file remains
7636 open during the whole autom4te run.
7637 ($icache_file): New.
7638 (&freeze): Lock the $icache_file.
7640 2003-04-29 Derek Price <derek@ximbiot.com>
7642 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7643 seperator with m4_append_uniq(). It doesn't work.
7644 (AT_CLEANUP): Add `;' to end of at_help_all.
7645 (AT_INIT): Allow --keywords to be specified more than once. When
7646 grepping $at_help_all for keywords, use the field and keyword
7647 seperators to ensure a complete keyword match. Alter at_prev handling
7648 to support the new --keywords behavior.
7650 2003-04-27 Karl Berry <karl@freefriends.org>
7652 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7653 align better with others. I also made some of the individual
7654 entries on one line, for brevity and to make it easier for me to
7655 sort my dir-example file in the Texinfo distribution :).
7657 2003-04-12 Jim Meyering <jim@meyering.net>
7659 * NEWS: Mention the new macro.
7660 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
7661 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
7662 * tests/c.at: Test AC_C_RESTRICT.

7675 2003-04-08 Akim Demaille <akim@epita.fr>
7677 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
7678 net/if.h, stdlib.h.

7690 2003-04-01 Akim Demaille <akim@epita.fr>
7692 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
7693 (AC, AT, MS): these.
7694 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
7695 New.
7696 Use them.
7697 * doc/Makefile.am (CLEANFILES): Adjust.
7698 (TEXI2DVI): Make it --batch.
7700 2003-03-31 Derek Price <derek@ximbiot.com>
7702 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7703 which removed the main loop.
7704 Thanks to Akim Demaille.
7706 2003-03-29 Akim Demaille <akim@epita.fr>
7708 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
7709 that starts a GUI.
7710 From Ilya Zakharevich.
7712 2003-03-29 Akim Demaille <akim@epita.fr>
7714 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
7715 documentation to read is Autoconf's.
7716 Suggested by Paul Eggert.
7718 2003-03-28 Akim Demaille <akim@epita.fr>
7720 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7721 reading the section "Present But Cannot Be Compiled" when the
7722 header causes problems.
7724 2003-03-28 Akim Demaille <akim@epita.fr>
7726 * tests/torture.at (Configuring subdirectories): Require aclocal
7727 1.4, otherwise the test fails, as it does support configure.ac.
7728 This fixes the "test 40 failed" bug reports.
7730 2003-03-28 Akim Demaille <akim@epita.fr>
7732 * doc/autoconf.texi (C Compiler): `#line' portability.
7733 From Paul Eggert and Nelson H. F. Beebe.
7735 2003-03-27 Derek Price <derek@ximbiot.com>
7737 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7738 layout in order to allow scripting around test groups.
7740 2003-03-27 Derek Price <derek@ximbiot.com>
7742 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7743 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7744 use new diversions in preparation for accepting new arguments and

7801 (Automake): Automake 1.5+ no longer requires special tools to be
7802 present on the developer's host.
7804 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>

7818 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7819 to cope with DOS-style absolute paths, when constructing
7820 ${ac_make}.
7822 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7823 When constructing paths with IFS=:, quote the path. If we're
7824 constructing a DOS-style absolute path, we don't want to split it
7825 on the colon.
7827 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo

7848 format starting with "-".
7850 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7852 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7853 is not portable inside Makefile.
7855 2003-02-20 Akim Demaille <akim@epita.fr>
7857 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7858 compiler says yeah, but preproc says nope, compiler is right.
7859 Conversely, prompt the reader to send a bug report to the
7860 maintainers of the package, not of Autoconf.
7862 2003-02-20 Klee Dienes <kdienes@apple.com>

7875 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7876 innocuous variant befor including <limits.h> or <assert.h>. This
7877 works around a bug reported by Albert Chin: HP-UX 11i
7878 (and earlier versions) have a <limits.h> that declares
7879 gettimeofday and many other functions.
7881 2002-12-03 Paul Eggert <eggert@twinsun.com>
7883 Version 2.57.
7885 * NEWS, configure.ac: Update version.
7887 * doc/fdl.texi: Upgrade to FDL version 1.2.
7889 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7890 nontrivially in main's body, so that f's external declaration is
7891 not optimized away in AIX. This should fix the bug reported by
7892 Martin Frydl in
7893 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7895 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7896 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7897 defined, to support freestanding compilers. This should fix the
7898 bug reported by Momchil Velkov in

7925 * configure.ac (AM_INIT_AUTOMAKE): here.
7926 Require 1.7.1.
7928 2002-11-14 Akim Demaille <akim@epita.fr>
7930 Version 2.55.
7932 * config/config.guess, config/config.sub, config/install-sh:
7933 Update from masters.
7935 2002-11-14 Akim Demaille <akim@epita.fr>
7937 * Makefile.maint: Sync with Bison, i.e.:
7938 (po-check): Scan .l and .y files instead of the
7939 .c and the .h files that they generate. This fixes the bug
7940 reported by Tim Van Holder in:
7941 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7942 Look for N_ as well as for _. Try to avoid matching #define for
7943 N_ and _.
7944 From Paul Eggert.
7946 2002-11-14 Akim Demaille <akim@epita.fr>
7948 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7949 From Paul Eggert and Albert Chin-A-Young.
7951 2002-11-14 Akim Demaille <akim@epita.fr>

7954 From Paul Eggert and Albert Chin-A-Young.
7956 2002-11-14 Kevin Ryde <user42@zip.com.au>
7958 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7959 than assigning in main, to avoid HP cc +O3 optimizing it away.
7961 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7963 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7964 option. Process --recheck after parsing all options. Pass -q
7965 option to configure on --recheck.
7966 (AC_OUTPUT): Pass -q from configure to config.status.

7970 config.status -q option.
7972 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

7997 Reported by Ezra Peisach.
7999 2002-11-05 Akim Demaille <akim@epita.fr>
8001 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
8002 Remove.
8003 We _have_ to stop using the old compatibility scheme that tried to
8004 avoid useless backslashes because Libtool 1.4.3 contains a
8005 AC_DEFINE([error_t], [int],
8006 [Define to a type to use for \`error_t' if it is not
8007 otherwise available.])
8008 We _have_ to quote the single quote and backslashes with \. The
8009 old compatibility scheme saw that ` was backslashed, and therefore
8010 did not quote the single quote. Hence before this patch, Autoconf
8011 was not compatible with Libtool.
8013 2002-11-04 Paul Eggert <eggert@twinsun.com>
8015 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8020 2002-11-04 Akim Demaille <akim@epita.fr>
8022 Version 2.54c.
8024 * Makefile.maint (update, cvs-update, po-update, do-po-update):
8025 New.
8026 * config/texinfo.tex: Update.
8028 2002-11-03 Akim Demaille <akim@epita.fr>
8030 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8031 from...
8032 (&autoreconf): here.
8033 ($help, $make, &parse_args, &autoreconf_current_directory):
8034 Support -m/--make.
8035 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8051 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
8053 2002-10-31 Akim Demaille <akim@epita.fr>
8055 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8056 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8057 Make variable, not a shell variable.
8058 Suggested by Bruno Haible.
8060 2002-10-31 Akim Demaille <akim@epita.fr>
8062 * bin/autom4te.in (load_configuration): Reject #args out of any
8063 language.
8065 2002-10-31 Akim Demaille <akim@epita.fr>
8067 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
8068 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

8079 Suggested by Tim van Holder.
8081 2002-10-29 Paul Eggert <eggert@twinsun.com>
8083 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8084 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8085 Problem reported by Bruno Haible.
8087 2002-10-29 Akim Demaille <akim@epita.fr>
8089 * doc/autoconf.texi (Header Templates): Put also in words what the
8090 pictures says to assist free style readers.
8091 (Customizing autom4te): s/--cache=/--cache /.
8093 2002-10-29 Akim Demaille <akim@epita.fr>
8095 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8096 sys/wait.h.
8097 sparc_address_test returns void.
8098 Use it with an argument, as prototyped.
8099 From Bruno Haible.
8101 2002-10-29 Akim Demaille <akim@epita.fr>
8103 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

8115 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
8116 * doc/autoconf.texi (Invoking autom4te): Rename as...

8320 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Avoid duplicates in
8321 `$ac_configure_args'.

8325 * doc/autoconf.texi: Use AC_CONFIG_HEADERS in examples.
8326 (AC_ST_BLKSIZE, AC_ST_RDEV): Directly point to AC_CHECK_MEMBERS.

8343 2002-10-22 Akim Demaille <akim@epita.fr>
8345 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
8346 are a few warnings.
8347 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
8348 Quote for Perl '' strings, not "".
8349 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8350 strings.
8352 2002-10-22 Akim Demaille <akim@epita.fr>
8354 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
8355 characters is a syntax warning now.

8362 `@', to tickle Perl's lists.
8363 Reported by Carlos Velasco.
8365 2002-10-18 Akim Demaille <akim@epita.fr>
8367 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

8377 2002-10-17 Akim Demaille <akim@epita.fr>
8379 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
8380 Fixes the `AC_ARG_VAR' test failures.

8400 Because of caching, some files that no longer exist and are no
8401 longer required can still cause errors.
8402 Reported by Alexandre Duret-Lutz.
8404 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8405 to frozen files in @ARGV, as @ARGV must remain being a list of
8406 files. Rather, at M4 call sites, use this...
8407 (&files_to_options): New function.
8408 (&freeze): Use &error.
8409 (&up_to_date): If a file that was included according to the cache
8410 is no longer there, then the output is out dated.
8411 (&main): Don't even check whether a file is up to date is anyway
8412 --force is given.
8413 * tests/tools.at (autom4te cache): New.
8415 2002-10-16 Akim Demaille <akim@epita.fr>
8417 * bin/autoconf.as: Kill dead options.
8418 * bin/autoupdate.in (&parse_args): Kill old options.
8419 * bin/autoreconf.in (&parse_args): Remove dead options.
8420 Factor some code.
8421 (&autoreconf): Report the directories we enter *and leave*, so
8422 that error messages can be easily located, and use GNU Make
8423 format, so that Emacs' compile mode understands us.
8424 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8425 if some file was changed instead of `print'.
8426 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8427 (&parse_args): Remove the dead options.
8428 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

8434 2002-10-11 Akim Demaille <akim@epita.fr>

8437 check for compilability.
8439 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8440 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

8444 * lib/autotest/general.m4 (AT_INIT): Include the failed test

8457 2002-10-11 Akim Demaille <akim@epita.fr>
8459 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8460 file name to enable parallel executions.
8461 From Sam Varshavchik.
8463 2002-10-08 Akim Demaille <akim@epita.fr>
8465 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8466 aclocal invocation, as Gettext macros might not be visible to
8467 aclocal.
8468 Instead of blindly running autopoint, scan configure.ac (not the
8469 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8470 Reported by Paul D. Smith.
8472 2002-10-08 Paul Eggert <eggert@twinsun.com>
8474 Work around problems found when POSIXLY_CORRECT=1 is set.
8475 None of this seems to have anything to do with POSIX, really,
8476 but it's how Perl getopt works.
8477 * bin/autom4te.in (parse_args): Configure GetOpt with
8478 "permute", too.
8479 * doc/autoconf.texi (Invoking autom4te):
8480 --warning -> --warnings.
8481 * lib/autom4te.in: --warning -> --warnings.
8483 2002-09-28 Akim Demaille <akim@epita.fr>

8500 2002-09-28 Akim Demaille <akim@epita.fr>
8502 * tests/torture.at (Configuring subdirectories): Be robust to
8503 users who use config.site to require for a cache: in this case,
8504 the two last configure runs, using two different sets of
8505 arguments, trigger a legitimate error.
8507 2002-09-28 Akim Demaille <akim@epita.fr>
8509 * tests/m4sh.at (Functions Support, Functions and return Support):
8510 New.

8518 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8520 2002-09-28 Akim Demaille <akim@epita.fr>

8523 (tm_zone): Move their rules to...
8524 * lib/autoconf/types.m4: here, using AN_ macros.
8525 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8526 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8527 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8528 * lib/autoconf/programs.m4: here.
8529 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
8530 (ETAGS_FOR_AUTOCONF): New.
8531 Use it.
8533 2002-09-28 Akim Demaille <akim@epita.fr>

8540 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8541 (.m4.m4f): Don't pass --prepend-include, since that's done by
8542 tests/autom4te itself.
8543 * lib/autoscan/Makefile.am: Include freeze.mk.
8544 (autoscan.list): New target --this file is no longer a source.
8545 (autoscan.pre): New file.
8547 2002-09-28 Akim Demaille <akim@epita.fr>
8549 * bin/autoscan.in (@kinds): Make them singular.
8550 Adjust all uses.
8551 (&init_tables): When --debug, report the list of rules to ease
8552 tracking changes in autoscan.list.
8553 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8555 2002-09-28 Akim Demaille <akim@epita.fr>
8557 * lib/autoscan/functions, lib/autoscan/headers,
8558 * lib/autoscan/identifiers, lib/autoscan/makevars,

8561 * bin/autoscan.in (&init_tables): Adjust.
8563 2002-09-28 Akim Demaille <akim@epita.fr>
8565 * lib/autoscan/functions, lib/autoscan/headers,
8566 * lib/autoscan/identifiers, lib/autoscan/makevars,
8567 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8568 `functions' line is now prefixed with `function:'.
8569 * bin/autoscan.in (&init_tables): Adjust.
8571 2002-09-28 Akim Demaille <akim@epita.fr>
8573 From now on, autoscan files must always map a macro name to a
8574 word: there is no `default' macro for autoscan.
8576 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8577 all.
8578 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8579 explicit.
8581 2002-09-28 Akim Demaille <akim@epita.fr>
8583 * bin/autoscan.in (%c_keywords): Remove.
8584 (&used): Keep only track of the words we might be interested in.
8585 (&output_kind): It is no longer needed to look for non active
8586 checks.

8615 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8616 Reported by Ralf Corsepius.
8617 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8619 2002-09-26 Akim Demaille <akim@epita.fr>
8621 Single suffix rules and seperated dependencies are not portable.
8623 * doc/autoconf.texi (Installation Directory Variables): Update.
8624 (Limitations of Make): Some about `Single Suffix Rules and
8625 Separated Dependencies'.

8629 2002-09-25 Paul Eggert <eggert@twinsun.com>
8631 * BUGS (Interoperability bugs): New section. Mention libtool
8632 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8634 2002-09-24 Paul Eggert <eggert@twinsun.com>

8637 make handles suffix-rules differently from GNU make.
8639 * bin/Makefile.am (SUFFIXES, .in): Remove.
8640 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

8643 2002-09-16 Akim Demaille <akim@epita.fr>
8645 i960 compilers create `b.out' files by default.
8646 Reported by Ralf Corsepius.
8648 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

8667 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8668 reading config.log when the compiler is rejected.
8669 Suggested by Guido Draheim.
8671 2002-09-13 Akim Demaille <akim@epita.fr>
8673 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8674 (chdir_init) might hang when stat'ing mounted directories.
8675 Reported by Vance Shipley.
8677 2002-09-12 Akim Demaille <akim@epita.fr>
8679 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8680 the lists.
8682 2002-09-12 Akim Demaille <akim@epita.fr>
8684 * doc/autoconf.texi (Defining Symbols): Present two different
8685 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

8690 * doc/autoconf.texi: Review grammar and punctuation.
8692 2002-09-11 Paul Eggert <eggert@twinsun.com>

8695 grammatical typos.
8696 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8697 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8698 is obsolescent.
8700 2002-09-11 Akim Demaille <akim@epita.fr>
8702 * doc/autoconf.texi (Questions): Rename as...
8703 (FAQ): this.

8716 2002-09-09 Akim Demaille <akim@epita.fr>
8718 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8719 `duplicates', since the algorithm was too naive and could keep
8720 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8721 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8722 Reported by Ralf Corsepius.
8723 * tests/torture.at (Configuring subdirectories): Exercise these
8724 cases.
8726 2002-09-09 Akim Demaille <akim@epita.fr>

8729 looking for a replacement file.
8730 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8731 directory is relative.
8732 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8733 directory definition.
8734 Reported by Andreas Schwab and Jim Meyering.
8736 2002-09-06 Akim Demaille <akim@epita.fr>

8739 precious variables are.
8740 Suggested by Pontus Skoeld.
8742 2002-09-05 Akim Demaille <akim@epita.fr>
8744 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8745 (ifnames, autoscan, autom4te): Since we don't only depend on
8746 configure.ac variables (such as VERSION etc.), but also on prefix
8747 and so forth, depend on Makefile, not configure.ac.
8748 Reported by Alexandre Duret-Lutz.
8749 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8751 2002-09-05 Kevin Ryde <user42@zip.com.au>
8753 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8754 doesn't seem to be confined to ia64, just say "some versions".
8756 2002-09-04 Akim Demaille <akim@epita.fr>
8758 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8759 Automake 1.6c.
8760 * Makefile.am (maintainer-clean-local): Remove.
8761 (MAINTAINERCLEANFILES): Remove COPYING.
8763 2002-09-03 Paul Eggert <eggert@twinsun.com>
8765 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8766 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8767 Brinkmann.
8769 2002-09-03 Akim Demaille <akim@epita.fr>
8771 * configure.ac: Bump to 2.53d.
8772 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8773 as of today, on Automake's team suggestion.
8775 2002-09-03 Akim Demaille <akim@epita.fr>
8777 Version 2.53c.
8779 2002-09-02 Akim Demaille <akim@epita.fr>
8781 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8782 SITE_MACRO_DIR.
8783 * configure.ac: Disable SITE_MACRO_DIR.
8785 2002-09-02 Jim Meyering <meyering@lucent.com>
8787 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8788 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8789 Also, tweak grammar: s/make sure to/be sure to/.
8791 2002-09-02 Paul Eggert <eggert@twinsun.com>
8793 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8794 directory names are generally preferable to physical names.
8796 2002-09-02 Akim Demaille <akim@epita.fr>
8798 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8799 Reported by Raja R. Harinath.
8800 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8801 * bin/autoupdate.in: Use error instead of die.
8803 2002-09-01 Paul Eggert <eggert@twinsun.com>
8805 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8806 ordinary shell concatenation rather than echo+tr+sed command that
8807 runs afoul of a long-line-related sed bug in Solaris 8.
8809 * bin/autoheader.in (parse_args): --warning -> --warnings.
8811 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8812 stdout, as traditional "ls" does.
8813 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8814 _AC_COMPILER_EXEEXT_O): Likewise.
8815 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8817 * bin/autoconf.as: Add --prepend-include option. This patch was
8818 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8819 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8821 * bin/autoconf.in, configure: Regenerate.
8823 * doc/autoconf.texi (Special Shell Variables): Mention
8824 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8826 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8827 MAILPATH and set PS1, PS2, PS4 to default values, to work
8828 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8829 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8830 the Autoconf documentation specifies; fall back to "unset" only if
8831 this fails. Use a shell for-loop for this rather than an m4 loop,
8832 to shorten the output script.
8834 2002-08-30 Paul Eggert <eggert@twinsun.com>
8836 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8837 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8838 for the CDPATH problem. Document PWD.
8839 (Limitations of Builtins): Document the problem that "cd $foo" and
8840 "ls $foo" may refer to different directories in shells conforming
8841 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8842 example, since the old example is now out of date.
8844 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8845 FOO" and "ls FOO" talk about different directories; this catches
8846 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8847 spaghetti.
8849 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8850 of rolling our own unset.
8851 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8852 in practice we needn't worry about CDPATH if unset doesn't work.
8854 * Makefile.in, aclocal.m4, bin/Makefile.in,
8855 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8856 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8857 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8858 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8859 tests/Makefile.in: Regenerate with Automake 1.6.3.
8861 * config/config.guess, config/config.sub, config/mkinstalldirs:
8862 Update.
8864 * configure: Regenerate with self.
8866 2002-08-30 Kevin Ryde <user42@zip.com.au>
8868 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8869 default output.
8871 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8873 * bin/autom4te.in (Request::load): Correctly test for "do" read
8874 failure.
8876 2002-08-29 Akim Demaille <akim@epita.fr>
8878 * lib/Autom4te/General.pm (&xqx): New.
8879 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8880 hand, which is not portable.
8881 (&error): New.
8882 * bin/autom4te.in: Use them.
8883 Use &error instead of die.
8884 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8885 Adjust.
8887 2002-08-17 Paul Eggert <eggert@twinsun.com>
8889 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8890 default list of compilers to try, since it was long ago superseded
8891 by the ksh fc builtin. Suggested by Steven G. Johnson.
8893 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8895 * doc/autoconf.texi (Invoking autom4te): End the option table,
8896 fixing a bug introduced by the previous patch.
8897 (Limitations of Make): Add a 'target lookup' subentry in the
8898 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8900 2002-07-29 Mark D. Roth <roth@feep.net>
8902 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8903 options and use $AUTOM4TE_PATH.
8904 * doc/autoconf.texi: Remove documentation of autom4te
8905 --include-envvar and --site-macro-subdir options and document
8906 use of $AUTOM4TE_PATH.
8907 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8908 arguments from each language section.
8910 2002-07-29 Paul Eggert <eggert@twinsun.com>
8912 * doc/install.texi: Include copyright symbol in copyright notice.
8914 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8915 Replace with:
8916 (AM_MAKEINFOFLAGS): New macro.
8917 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8918 * Makefile.am (INSTALL): Use the new macros.
8919 Use -o rather than --output, since "missing" does not grok --output.
8921 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8923 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8924 comments do not always work. Never trust the exit status of
8925 `make -k'.
8927 2002-07-24 Kevin Ryde <user42@zip.com.au>
8929 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8930 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8932 2002-07-23 Paul Eggert <eggert@twinsun.com>
8934 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8935 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8936 apparently treats PATH="nonexistent" as if it contained ".".
8937 Bug reported by Stefan `Sec' Zehl.
8939 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8941 * doc/autoconf.texi (Limitations of Make): Mention the special
8942 handling of the obj/ directory by BSD make.

8958 2002-07-18 Akim Demaille <akim@epita.fr>
8960 Version 2.53b.
8962 2002-07-18 Akim Demaille <akim@epita.fr>
8964 * config/config.guess, config/config.sub: Update.
8966 2002-07-18 Akim Demaille <akim@epita.fr>

9092 on Solaris 2.5.1.
9094 2002-06-11 Andreas Schwab <schwab@suse.de>

9098 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9100 * bin/autom4te.in ($cache): Don't define using `$me', the name

9102 was installed.
9104 2002-06-07 Akim Demaille <akim@epita.fr>

9207 This improves on an earlier suggestion by H. Peter Anvin.
9209 2002-05-16 Paul Eggert <eggert@twinsun.com>
9211 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9212 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9213 Both macros now accept an optional source-dir arg.
9214 New macro AC_GNU_SOURCE to define _GNU_SOURCE.

9219 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.

9223 Add new optional argument DIR.
9224 (AC_FUNC_FNMATCH_GNU): New macro.
9226 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9228 2002-05-08 Paul Eggert <eggert@twinsun.com>
9230 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9231 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9232 and it causes a 'test' syntax error if it fails.
9233 Bug reported by Stephen Gildea.
9235 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9236 If prototypes are supported, use them to check this at compile-time,
9237 instead of trying to check it at run-time. If we must do a run-time
9238 check, assume that setvbuf is standard when cross-compiling, as
9239 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9240 Bug reported by Paul D. Smith.
9242 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9243 argument specifying location of getloadavg.c. This removes a
9244 FIXME. This idea was taken from Jim Meyering's implementation in
9245 textutils.
9246 * doc/autoconf.texi (Particular Functions): Document this.
9247 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9248 that's what the code does; this fixes a bug reported by
9249 Paul D. Smith.
9251 2002-05-03 Akim Demaille <akim@epita.fr>
9253 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9254 autopoint instead of gettextize.
9255 ($uses_alocal): Rename as...
9256 ($uses_aclocal): this.
9257 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9258 Suggested by Bruno Haible.
9260 2002-05-03 Akim Demaille <akim@epita.fr>
9262 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9264 2002-04-29 Paul Eggert <eggert@twinsun.com>
9266 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9267 files to be 1 second older; just set them to be the same time.
9268 Also, sleep 1 second after the first aclocal, to work around
9269 problems with sub-second time stamps on the input files.
9271 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9273 * doc/autoconf.texi: Mention "set -e -x" lossage
9274 under node "Limitations of Builtins".
9276 2002-04-29 Akim Demaille <akim@epita.fr>
9278 * doc/install.texi: Better wording for setting variables when
9279 running configure.
9280 From Christian Cornelssen.
9282 2002-04-29 Akim Demaille <akim@epita.fr>
9284 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9285 of lack of $LINENO support, then the test will compare the $LINENO
9286 in testsuite vs. the lineno in the test file. This is wrong, of
9287 course.
9288 Be sure to protect it.
9289 Reported by Patrick Welche.
9291 2002-04-25 Akim Demaille <akim@epita.fr>
9293 * doc/autoconf.texi (Obsolete Macros): Typo.
9294 Reported by Vladimir Volovich.
9296 2002-04-25 Akim Demaille <akim@epita.fr>
9298 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9299 than some of the input files, hence, on the second run of aclocal,
9300 if some of its input are younger, make them older.
9301 Suggested by Paul Eggert.
9303 2002-04-25 Akim Demaille <akim@epita.fr>
9305 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9306 Thanks to Paul Eggert.
9308 2002-04-25 Akim Demaille <akim@epita.fr>
9310 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9311 and ac_subst_vars be sh variables containing the list of
9312 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9313 DEFAULT diversion.
9314 (_AC_INIT_PREPARE): Use them to log them.
9315 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9316 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9317 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9318 _AC_SUBST_FILES and _AC_SUBST_VARS.
9319 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9321 2002-04-24 Akim Demaille <akim@epita.fr>
9323 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9324 autoheader, so that automake does not complain about a missing
9325 config.h.in that was to be created.
9327 2002-04-23 Akim Demaille <akim@epita.fr>
9329 * bin/autoheader.in (parse_args): --warning takes an argument.
9330 Fixes PR/220.
9332 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9334 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9335 and bb.out when cleaning up.
9337 2002-04-22 Akim Demaille <akim@epita.fr>
9339 Version 2.53a.
9341 2002-04-22 Akim Demaille <akim@epita.fr>
9343 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9345 2002-04-22 Akim Demaille <akim@epita.fr>
9347 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9348 comma.
9349 Reported by Gregory Giannoni.
9351 2002-04-22 Akim Demaille <akim@epita.fr>
9353 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9354 Fixes false failures on Darwin.
9356 2002-04-21 Paul Eggert <eggert@twinsun.com>

9360 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9378 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
9379 Minor spelling and grammar fixes.
9381 * doc/autoconf.texi: Follow the outline suggested in the GNU
9382 Sample Texts sections of the Texinfo 4.2 manual. Most
9383 importantly, this makes sure that the copyright notices appear in
9384 all output formats. You probably need Texinfo 4.2 to generate
9385 the manual now.
9387 Fix some bugs when using "$@" when there might be zero positional
9388 arguments in cases where this matters.
9390 * bin/autoconf.as: Rewrite so that the problem does not come up.

9405 Use Zsh alias to work around problem.
9406 * tests/atgeneral.m4 (AT_INIT): Likewise.
9408 * tests/c.at: We can't have zero arguments, so remove workaround
9409 that is not portable to Zsh.
9411 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9413 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9414 from aclocal.m4 too.
9416 2002-04-12 Akim Demaille <akim@epita.fr>
9418 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9420 2002-04-10 Akim Demaille <akim@epita.fr>
9422 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9423 workaround for ${1+"$@"}.
9424 * doc/autoconf.texi (Shell Substitutions): Explain it.
9425 From Oliver Kiddle and Peter Stephenson.
9427 Have M4sh perform minimal shell sanitizing.
9429 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9430 part into...
9431 (_AS_PREPARE): this new macro.
9432 (AS_PREPARE): New.
9433 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9434 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9436 Adjust Autoconf and Autotest.
9438 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9439 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9440 * lib/autotest/general.m4 (AT_INIT): Likewise.
9441 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9442 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9443 AS_SHELL_SANITIZE.
9445 Use this M4sh to generate Autoconf's shell scripts.
9447 * tests/wrapsh.as: New, precursor of wrapsh.in.
9448 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9449 on Autotest and M4sh.
9450 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9451 (wrapsh.in): New target.
9452 * bin/autoconf.as: New, precursor of autoconf.in.
9453 (autoconf.in): New target.
9455 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9458 with indented comments in rules.
9460 2002-04-09 Andreas Schwab <schwab@suse.de>
9462 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9463 ac_top_builddir when setting ac_abs_top_builddir.
9465 2002-04-06 Kevin Ryde <user42@zip.com.au>
9467 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9468 (Portable Shell): Cross reference to Systemology.
9470 2002-04-05 Akim Demaille <akim@epita.fr>
9472 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9473 directories when descending in a SUBDIRS.
9474 Reported by Ezra Peisach.
9476 2002-04-04 Andreas Schwab <schwab@suse.de>
9478 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9479 contains no literal separators.
9481 2002-04-03 Akim Demaille <akim@epita.fr>
9483 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9484 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9485 Use dnl, not the KILL diversion.
9486 Extracted from...
9487 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9488 (AC_CONFIG_LINKS): here.
9489 Adjust.
9490 Don't use the KILL diversion, as it kills spurious output, which
9491 results in failures being hidden.
9492 Use m4_defn where appropriate.
9493 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9494 after the second argument.
9495 Use m4_defn.
9496 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9497 syntax, as it is provided by M4sugar.
9498 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9500 2002-04-03 Andreas Schwab <schwab@suse.de>
9502 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9503 expanded if $# <= 2.
9505 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9506 aclocal.
9508 2002-04-03 Akim Demaille <akim@epita.fr>
9510 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

9512 Also recognize *.bb and *.bbg as compilation byproducts.
9513 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9514 (_AC_COMPILER_OBJEXT): Use them.
9515 Fixes Debian #138666.
9517 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9519 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9521 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9522 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9523 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9524 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9525 (AC_C_CONST): Same.
9526 (AC_C_INLINE): Same.
9527 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9528 * doc/autoconf.texi, NEWS: Document.
9529 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9530 AC_C_CROSS.

9535 _AS_MKDIR_P_PREPARE.
9537 2002-03-28 Kevin Ryde <user42@zip.com.au>
9539 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9540 to avoid versions of HP C which don't allow that.
9542 2002-03-27 Paul Eggert <eggert@twinsun.com>
9544 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9545 (AS_SHELL_SANITIZE): Invoke it.
9546 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9548 2002-03-26 Akim Demaille <akim@epita.fr>
9550 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9552 2002-03-26 Akim Demaille <akim@epita.fr>
9554 * doc/autoconf.texi (Introduction): The GNATS base moved.
9556 2002-03-25 Paul Eggert <eggert@twinsun.com>
9558 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9559 as POSIX requires, as it doesn't work with Zsh.
9560 * doc/autoconf.texi (Assignments): Document the problem.
9562 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9564 * doc/autoconf.texi (Limitations of Make): Mention more issue
9565 about VPATH, overriding of macros in sub-makes, and handling of
9566 SHELL.
9568 2002-03-21 Paul Eggert <eggert@twinsun.com>
9570 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9571 problem with here-document buffer boundaries.
9573 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9574 when reinvoking the shell, to work around problems with installers
9575 who put strange things like "cd" commands in their environments.
9577 2002-03-19 Akim Demaille <akim@epita.fr>
9579 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9580 From Aaron Ucko.
9582 2002-03-19 Akim Demaille <akim@epita.fr>
9584 * bin/autoscan.in (scan_file): Specify the location in `&used'
9585 invocations.
9586 From Nicolas Joly.
9588 2002-03-19 Akim Demaille <akim@epita.fr>
9590 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9591 From Nishio Futoshi.
9593 2002-03-19 Akim Demaille <akim@epita.fr>
9595 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9597 2002-03-18 Paul Eggert <eggert@twinsun.com>
9599 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9600 (Limitations of Usual Tools): Add mkdir section.
9602 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9603 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9604 back on AS_DIRNAME to compute prefixes otherwise; this is
9605 roughly what mkinstalldirs does. That way, we need not have
9606 our own filename disassembler. The old disassembler did not
9607 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9609 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9610 Create at_test_all by a series of assignments,
9611 not by a single assignment of a long string. The latter causes ksh
9612 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9613 presumably because of a buffer overrun.
9615 2002-03-14 Paul Eggert <eggert@twinsun.com>
9617 * lib/autotest/general.m4 (at_times_skip):
9618 Renamed from at_times. Now a boolean.
9619 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9620 says 'times: not found'.
9622 2002-03-14 Akim Demaille <akim@epita.fr>
9624 * bin/autoreconf.in (&study_gettextize): New.
9625 (&autoreconf): Handle newest gettextize.
9626 Rerun aclocal if needed.
9627 Suggested by Andreas Schwab.
9629 2002-03-13 Akim Demaille <akim@epita.fr>
9631 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9633 2002-03-13 Akim Demaille <akim@epita.fr>
9635 * doc/autoconf.texi (Header Portability): New.
9636 Add information about stdint.h and inttypes.h from Paul Eggert.
9638 2002-03-13 Akim Demaille <akim@epita.fr>
9640 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9641 -p'.
9642 From Bob Proulx.
9644 2002-03-12 Akim Demaille <akim@epita.fr>
9646 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9647 m4_require.
9649 2002-03-11 Andreas Schwab <schwab@suse.de>
9651 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9652 does not do it if --with-lispdir is given.
9654 2002-03-08 Akim Demaille <akim@epita.fr>
9656 Version 2.53.
9658 2002-03-08 Akim Demaille <akim@epita.fr>
9660 * doc/autoconf.texi (Subdirectories): Clarify that the
9661 subdirectory should exist.
9663 2002-03-08 Akim Demaille <akim@epita.fr>
9665 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9667 2002-03-08 Akim Demaille <akim@epita.fr>
9669 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9670 aliases the actual variables, and modifications of the former
9671 affect the latter.
9673 2002-03-08 Akim Demaille <akim@epita.fr>
9675 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9676 because of C-c: have m4 output in tmp files, then mv them.
9678 2002-03-08 Akim Demaille <akim@epita.fr>
9680 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9681 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9682 * bin/ifnames.in: Copyright update.
9684 2002-03-08 Akim Demaille <akim@epita.fr>
9686 * doc/autoconf.texi (Invoking autom4te): New.
9688 2002-03-05 Akim Demaille <akim@epita.fr>
9690 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9691 Kevin Ryde.
9693 2002-03-05 Akim Demaille <akim@epita.fr>
9695 Version 2.52i.
9697 2002-03-04 Akim Demaille <akim@epita.fr>
9699 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9700 * lib/autoconf/general.m4 (AC_INIT): More informative error
9701 message for LIBOBJ.
9703 2002-03-04 Akim Demaille <akim@epita.fr>
9705 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9706 parallel builds.
9708 2002-03-04 Akim Demaille <akim@epita.fr>
9710 * doc/autoconf.texi (Transforming Names): Equality between target
9711 and host is irrelevant.
9712 (Specifying Names, Canonicalizing): Remove all references to the
9713 backward compatibility hooks. Rather, collect them all into...
9714 (Hosts and Cross-Compilation): this new section.
9715 * doc/install.texi (System Type): Ditto.
9716 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9717 that `--host' implies cross-compilation.
9719 2002-03-04 Akim Demaille <akim@epita.fr>
9721 * doc/autoconf.texi (Evaluation Macros): New.
9722 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9723 useless.
9724 (_m4_foreach): Define the variant with immediate evaluation so
9725 that it contains exactly the items, not an expression which
9726 evaluation is the current item.
9727 (m4_re_string, m4_re_word): Don't over quote them.
9729 2002-03-04 Akim Demaille <akim@epita.fr>
9731 Instead of having stacking `shift's evaluated at the end, let
9732 `foreach' loops immediately evaluate them.
9734 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9735 $*. This is the n-th time I change my mind, but hopefully this is
9736 the last...
9737 (m4_lquote): New.
9738 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9739 efficient.
9740 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9741 it was only a hack for m4_text_wrap.
9742 (m4_car2): Remove, replaced by...
9743 (m4_cdr): New.
9744 (_m4_foreach): Adjust.
9745 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9746 m4_bpatsubst for clarification.
9748 2002-03-04 Akim Demaille <akim@epita.fr>
9750 * doc/autoconf.texi (Changequote is Evil): New.

9755 on old systems like SunOS.

9768 message to be sent.
9770 2002-02-28 Kevin Ryde <user42@zip.com.au>
9772 * doc/autoconf.texi (Function Portability): Add va_copy and va_list.
9774 2002-02-25 Akim Demaille <akim@epita.fr>
9776 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9777 From Akinori Musha.
9779 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9781 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9782 translate \r\n to \n.
9784 2002-02-07 Akim Demaille <akim@epita.fr>

9790 Fix Autoconf PR/209.
9791 Also reported by Frank Denis.
9793 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9795 2002-02-07 Akim Demaille <akim@epita.fr>
9797 Fix Autoconf PR/207:
9798 AC_PREFIX_PROGRAM fails with dashed program names
9800 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9801 variable when looking for the prefix program.
9802 Now it also works for shell variables.
9804 2002-02-07 Akim Demaille <akim@epita.fr>
9806 * doc/autoconf.texi (Limitations of Builtins): More about
9807 case/esac.
9809 2002-02-06 Akim Demaille <akim@epita.fr>
9811 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9812 case/esac, some shells don't support it.
9813 Reported by Zack Weinberg.
9814 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9816 2002-02-06 Akim Demaille <akim@epita.fr>
9818 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9819 sure not to introduce newlines in at_groups.
9820 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9822 2002-02-06 Akim Demaille <akim@epita.fr>
9824 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9825 is not available.
9827 2002-02-05 Paul Eggert <eggert@twinsun.com>
9829 * doc/autoconf.texi (Specific Compiler Characteristics):
9830 Describe HP-UX cc bug workaround more accurately.
9831 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9832 not unsigned long.
9833 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9834 cross-compilers, too. This undoes some of the most recent change
9835 to this file.
9837 2002-02-05 Akim Demaille <akim@epita.fr>
9839 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9840 to make sure they are up to date when `check' is run.
9842 2002-02-05 Akim Demaille <akim@epita.fr>
9844 * doc/autoconf.texi (Making testsuite Scripts): Document
9845 package.m4.
9847 2002-02-05 Akim Demaille <akim@epita.fr>
9849 * lib/freeze.mk: New.
9851 2002-02-05 Akim Demaille <akim@epita.fr>
9853 Implement `autom4te --freeze'.
9855 * bin/autom4te.in (&freeze): New.
9856 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9857 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9859 2002-02-05 Akim Demaille <akim@epita.fr>
9861 * bin/autom4te.in (&parse_args): Implement `frozen files are
9862 optional are the sum of the previous files on the command line'.
9863 Also, pass `--reload-state=' on them, so...
9864 (handle_m4): don't.
9865 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9866 (M4sh): Rely on M4sugar.
9867 (Autotest, M4sh, M4sugar): Use frozen files.
9869 2002-01-31 Akim Demaille <akim@epita.fr>
9871 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9872 * doc/autoconf.texi (Initializing configure): Adjust.
9874 2002-01-30 Akim Demaille <akim@epita.fr>
9876 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9877 alphanumeric to `-' instead of `_'.
9879 2002-01-30 Akim Demaille <akim@epita.fr>
9881 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9882 for plain code, the other for cross-compilation code. The latter
9883 is now run with GCC only.
9884 * doc/autoconf.texi (Compilers and Preprocessors): New.
9886 2002-01-30 Akim Demaille <akim@epita.fr>
9888 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9889 values.
9890 * doc/autoconf.texi (Initializing configure): Explain how to
9891 change AC_INIT default values.
9893 2002-01-29 Akim Demaille <akim@epita.fr>
9895 * tests/torture.at (Configuring subdirectories): Use configure.in,
9896 so that aclocal 1.4 works.
9897 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9899 2002-01-28 Akim Demaille <akim@epita.fr>
9901 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9902 needs an argument.
9904 2002-01-28 Akim Demaille <akim@epita.fr>
9906 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9907 AUTOTEST_PATH *after* it was set.
9908 Don't put `.' in the PATH: the user should be precise and `./' if
9909 needed. In addition, given that the test suite does some `cd', if
9910 `.' is in the path, the `tested programs' sections will report
9911 programs found in the test suite's directory, while during the
9912 tests (performed in their own directory), these programs are no
9913 longer visible. In other words, the results is confusing and
9914 useless.
9915 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9917 2002-01-24 Akim Demaille <akim@epita.fr>
9919 Version 2.52g.
9921 2002-01-24 Akim Demaille <akim@epita.fr>
9923 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9924 * doc/autoconf.texi: Finally add Akim as an author.
9926 2002-01-24 Akim Demaille <akim@epita.fr>
9928 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9929 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9930 Bourne. Use /bin/sh.
9931 From Andreas Buening.
9933 2002-01-24 Akim Demaille <akim@epita.fr>
9935 * config/config.guess, config/config.sub, config/texinfo.tex:
9936 Update from masters.
9938 2002-01-24 Akim Demaille <akim@epita.fr>

9943 * config/missing.m4, config/sanity.m4, config/select.m4,
9944 * config/strip.m4: Remove, to ease sync'ing with any version of
9945 Automake.
9947 2002-01-24 Akim Demaille <akim@epita.fr>
9949 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9950 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9951 Reported by Geir Ove Myhr.
9953 2002-01-21 Akim Demaille <akim@epita.fr>
9955 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9957 2002-01-21 Akim Demaille <akim@epita.fr>
9959 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9960 message on invalid options.
9961 * bin/autom4te.in (parse_args): Don't use
9962 Autoconf::General::getopt with non valid options.
9964 2002-01-17 Jim Meyering <meyering@lucent.com>
9966 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9967 $ac_cv_exeext so we don't use an old, invalid, cached value.
9969 2002-01-11 Akim Demaille <akim@epita.fr>
9971 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9972 Meyering.
9973 * doc/autoconf.texi (Function Portability): Document the strnlen
9974 limitation.

9976 * lib/autoscan/functions: Adjust.
9978 2002-01-06 Akim Demaille <akim@epita.fr>
9980 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9981 package.m4, since is really depends upon configure.ac, not
9982 configure.
9983 * doc/autoconf.texi (testsuite Scripts): Adjust.
9984 * tests/Makefile.am (package.m4): New.
9985 EXTRA_DIST it since its a source.
9987 2002-01-06 Akim Demaille <akim@epita.fr>
9989 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9990 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9991 and PACKAGE_BUGREPORT from here...
9992 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9993 arguments.
9994 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9995 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9996 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9997 * tests/tools.at (autoheader): Adjust.
9998 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
10000 2002-01-06 Akim Demaille <akim@epita.fr>
10002 * bin/autoscan.in (scan_file): Use `&used'.
10004 2002-01-03 Akim Demaille <akim@epita.fr>
10006 * doc/autoconf.texi (Output): Improved wording regarding use of
10007 AC_OUTPUT.
10008 From Olly Betts.
10010 2001-12-18 Kevin Ryde <user42@zip.com.au>
10012 * doc/autoconf.texi (Function Portability): Add notes on sscanf
10013 sometimes needing writable input.
10015 2001-12-17 Jim Meyering <meyering@lucent.com>
10017 * doc/autoconf.texi (New Macros): Tweak wording.
10019 2001-12-14 Akim Demaille <akim@epita.fr>
10021 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
10022 trailing files, don't apply `-rf' to files which might not be
10023 created by configure (core, core.*, and *.core), but just `rm -f'.
10024 Suggested by Jonathan Kamens.
10026 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
10028 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
10030 2001-12-14 Akim Demaille <akim@epita.fr>
10032 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
10034 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
10036 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
10037 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
10038 abs_srcdir, top_srcpath to abs_top_srcdir.
10039 (_AC_OUTPUT_FILES): Adjust.
10040 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
10041 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
10042 * tests/wrappl.in, tests/wrapsh.in: Adjust.
10044 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
10046 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
10047 C/Fortran linking on HP/UX, by extracting the Fortran library
10048 search path from the LPATH line in the $F77 -v output.
10050 2001-12-12 Kevin Ryde <user42@zip.com.au>
10052 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10053 forbidden file descriptors table.
10055 2001-11-26 Akim Demaille <akim@epita.fr>
10057 * bin/autoscan.in (%c_keywords): Build it at top level.
10058 Map to 1 in order to simplify its uses.
10060 2001-11-26 Akim Demaille <akim@epita.fr>
10062 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10063 Remove $filepath, useless.
10064 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10065 variables, they are really part of the tokens.
10066 Split the input line on spaces and then look for tokens.
10067 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10068 because of `lex$U.$(OBJEXT)'.
10069 (&scan_files): Use "@list" instead of join.
10070 * doc/Makefile.am (CLEANFILES): Add *.fns.
10072 2001-11-26 Akim Demaille <akim@epita.fr>
10074 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10075 Remove, replaced by...
10076 * tests/wrappl.in: Be common for all the Perl executables.
10077 In particular autoscan and autoheader want -I.
10078 * configure.ac: Adjust.
10079 * lib/autoscan/headers: errno.h is portable.
10081 2001-11-26 Akim Demaille <akim@epita.fr>
10083 * bin/autoscan.in (used): New.
10084 Use it.
10086 2001-11-26 Akim Demaille <akim@epita.fr>
10088 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10089 directives.
10090 (&scan_sh_file): Remove a duplicate pattern.
10091 (&check_configure_ac): Use long options.

10094 2001-11-26 Akim Demaille <akim@epita.fr>
10096 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10097 Before, having a line containing the opening of a multi line
10098 comment made the whole line be ignored.
10100 2001-11-26 Akim Demaille <akim@epita.fr>
10102 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10103 (testsuite Scripts): Be one of its subsection.
10104 (Autotest Logs): New.
10106 2001-11-26 Akim Demaille <akim@epita.fr>
10108 Test groups are now run two directories deeper.
10110 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10111 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10112 at_top_builddir.
10113 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10114 top_srcdir, builddir and top_builddir.
10115 Use `at_*dir' relatively to the directory containing the
10116 suite, use `*dir' when relatively to the current group dir.
10118 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10120 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10121 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10122 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10123 spelling errors.
10125 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10127 * doc/autoconf.texi (Using System Type): Add an example of `case
10128 $host' usage so people quit using `case $target' everywhere.
10130 2001-11-22 Akim Demaille <akim@epita.fr>
10132 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10133 spotted by Jim Meyering.
10135 2001-11-16 Paul Eggert <eggert@twinsun.com>
10137 This patch implements a `long double' suggestion by Oliver Kiddle.
10139 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10140 static, to catch errors if the value isn't known at compile-time
10141 and the compiler supports dynamic arrays. Change its name from
10142 `_array_' to `test_array' to avoid potential name clashes.
10143 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10144 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10145 better than double. Catch a bug in GCC 2.95.2 x86.
10146 * doc/autoconf.texi (C Compiler): Document the above.
10147 * NEWS: Likewise.
10149 2001-11-13 Akim Demaille <akim@epita.fr>
10151 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10152 hand.
10153 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10155 2001-11-13 Akim Demaille <akim@epita.fr>
10157 * lib/autotest/general.m4 (AT_INIT): After having run the test
10158 group, go back to the initial directory, not to at_suite_dir.
10160 2001-11-13 Akim Demaille <akim@epita.fr>
10162 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10163 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10164 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10165 option.
10166 (AT_CHECK_CONFIGURE): Use absolute paths.
10167 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10168 The problem is still the old one: there is no means in M4 (that I
10169 know about) to create a defining macro, because there is no means
10170 to create `$1' etc., therefore, the defining macro ``swallows''
10171 all the arguments meant to the defined macro.
10173 2001-11-13 Akim Demaille <akim@epita.fr>
10175 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10176 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10177 configure.ac.
10178 * tests/aclocal.m4: Remove, as it is no longer used.
10180 2001-11-13 Akim Demaille <akim@epita.fr>
10182 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10183 variable names when referring to a single test group, or to
10184 `suite' when referring to the whole test suite.
10185 `at_last_test' is removed: m4 compute at_format itself.
10186 (at_stdout, at_stder1, at_stderr): New variables.
10187 (AT_CHECK): Use them.
10189 2001-11-13 Akim Demaille <akim@epita.fr>
10191 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10192 in PATH.
10193 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10194 Do it as soon as a test fails, don't wait till the end of the test
10195 suite.
10196 Don't remove $as_me.[0-9]*, since these files no longer exist.
10198 2001-11-13 Akim Demaille <akim@epita.fr>
10200 * tests/tools.at: Use absolute paths, since we are no longer run
10201 in place.
10203 2001-11-13 Akim Demaille <akim@epita.fr>
10205 Now that tests are running in their own private dir, there is no
10206 need to list the files to remove at the end of tests groups.
10208 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10209 (AT_data_files, at_data_files): Remove.
10210 (AT_CLEANUP, AT_DATA): Simplify.
10211 (AT_INIT): Adjust.
10212 Remove the group dir if !debug && !failed.
10213 * tests/atspecific.m4: Adjust.
10215 2001-11-13 Akim Demaille <akim@epita.fr>
10217 Start a new layout for Autotest: `testsuite' creates
10218 `testsuite.dir' in which the at-check-line etc. files are to be
10219 found, and `testsuite.dir/003' where the test group 3 is run.
10221 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10222 at_check_line_file, at_format, at_test_normalized, at_group_dir
10223 are new variables.
10224 Create the directories.
10225 Use absolute paths for at- files.
10226 (AT_CHECK): Adjust.
10228 2001-11-11 Michael Matz <matz@kde.org>
10230 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10231 (m4_car2): New.
10232 (m4_car): Properly quote arguments.
10234 2001-11-13 Akim Demaille <akim@epita.fr>
10236 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10237 with stricter rules on LIBOBJS.
10239 2001-11-12 Paul Eggert <eggert@twinsun.com>
10241 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10242 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10243 __PROTOTYPES too.
10245 2001-11-12 Akim Demaille <akim@epita.fr>
10247 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10249 2001-11-12 Akim Demaille <akim@epita.fr>
10251 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,

10253 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10254 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10255 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10256 specify to what the macro should be defined (typically to 1).
10258 2001-11-12 Akim Demaille <akim@epita.fr>
10260 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10261 From Jim Meyering.
10263 2001-11-12 Akim Demaille <akim@epita.fr>
10265 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10266 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10267 definition used by Automake where LEX is +/- "${missing} lex" and
10268 `missing' itself contains variables.
10270 2001-11-12 Akim Demaille <akim@epita.fr>
10272 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10273 Now that M4sh pushes BODY, the comments were output at the end of
10274 the test suites.
10276 2001-11-08 Akim Demaille <akim@epita.fr>
10278 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10279 that we can trace macros from aclocal.m4.
10280 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10281 obsoleted, and redirect to the former anyway.
10282 Reported by Ralf Corsepius.
10284 2001-11-08 Akim Demaille <akim@epita.fr>
10286 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10287 processed only if present.
10288 * tests/torture.at (Configuring subdirectories): Use autoreconf
10289 instead of successive calls to autoconf.
10290 Add a nonexistent subdirectory to exercise the patch above.
10291 Reported by Ralf Corsepius.
10293 2001-11-08 Kevin Ryde <user42@zip.com.au>
10295 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10296 doesn't accept .S files.

10302 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10303 * bin/autom4te.in (warn_forbidden): New.
10304 (handle_output): Use it.
10305 Read m4_pattern_forbid with messages.
10307 2001-11-05 Akim Demaille <akim@epita.fr>
10309 * bin/autom4te.in (--normalize): Remove.
10310 * lib/autom4te.in: Adjust.
10312 2001-11-05 Akim Demaille <akim@epita.fr>
10314 * tests/Makefile.am (testsuite): Rename this target as...
10315 ($(TESTSUITE)): this.
10316 From Nicolas Joly.
10318 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10320 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10321 the --prefix option, also remove it's argument.
10323 2001-11-05 Akim Demaille <akim@epita.fr>
10325 * doc/autoconf.texi (testsuite Invocation): Update.
10326 (Writing testsuite.at): Update.
10328 2001-11-03 Akim Demaille <akim@epita.fr>
10330 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10332 2001-11-03 Akim Demaille <akim@epita.fr>
10334 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10335 (&file_name_is_absolute): New, wrappers around routines from
10336 File::Spec.
10337 Use and export them.
10338 (&find_configure_ac): Optionally take a directory where to look at.
10339 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10340 the arguments.
10341 Default @ARGV to `.', not find_configure_ac.
10342 (&autoreconf): Argument is a directory.
10343 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10344 * doc/autoconf.texi (autoreconf Invocation): Update.
10346 2001-11-03 Akim Demaille <akim@epita.fr>
10348 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10349 (@export_forward_subs): New.
10350 Add basename, dirname, and fileparse.
10351 (@EXPORT): Adjust.
10352 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10353 Don't look for aclocal flags if we already know aclocal is not
10354 used.
10355 Move aclocal.m4t only if it exists.
10356 Reported by Ezra Peisach.
10358 2001-11-03 Akim Demaille <akim@epita.fr>
10360 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10361 passed on command line, defaulting to ./configure.ac if present.
10362 (&maybe_autoreconf, File::Find): Remove, unused.
10363 (&autoreconf): If autoconf is not used, don't try to trace.
10365 2001-11-02 Akim Demaille <akim@epita.fr>
10367 * configure.ac: Bump to 2.52g.
10369 2001-11-02 Akim Demaille <akim@epita.fr>
10371 Version 2.52f.
10373 2001-11-02 Akim Demaille <akim@epita.fr>
10375 * config/config.guess, config/config.sub, doc/standards.texi:
10376 * config/lispdir.m4: Update from masters.
10377 * configure.ac: Bump to 2.52f.
10379 2001-11-02 Akim Demaille <akim@epita.fr>
10381 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10382 Don't run aclocal when aclocal.m4 is not from aclocal.
10383 From Ezra Peisach.
10384 Don't run libtoolize and gettextize if --install is not given.
10386 2001-11-01 Paul Eggert <eggert@twinsun.com>
10388 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10389 be invoked before _AS_LINENO_PREPARE.
10390 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10391 than character ranges.
10393 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10394 invoking AS_BASENAME. Set the locale variables to 'C' if
10395 possible, as POSIX requires this to get the traditional
10396 behavior.
10397 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10399 2001-10-31 Paul Eggert <eggert@twinsun.com>
10401 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10402 with {}, as that triggers a bug in Bash 2.05.
10404 (_AS_LINENO_PREPARE): Use Sed rather than
10405 Awk. Fix the sed prepass to work even if there are multiple
10406 instances of $LINENO on the same line. Do not substitute for
10407 other variables like $LINENOT. Do not check file dates; such a
10408 check is unreliable on sufficiently fast machines, and removing
10409 the check makes the code simpler and more reliable. Check for
10410 output and chmod failures.
10412 * doc/autoconf.texi (Special Shell Variables): Document
10413 the above.
10415 2001-10-31 Akim Demaille <akim@epita.fr>
10417 * tests/Makefile.am (atconfig): Remove this target, Automake
10418 handles it now.
10420 2001-10-31 Akim Demaille <akim@epita.fr>
10422 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10423 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10424 provided, while it is optional.
10425 * configure.ac: Adjust.
10427 2001-10-26 Paul Eggert <eggert@twinsun.com>
10429 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10430 lib/Autom4te/Struct.pm:
10431 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10432 with 5.005_02.
10434 * doc/autoconf.texi (Special Shell Variables): Document some
10435 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10437 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10438 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10439 eval $LINENO is not portable in practice.
10441 2001-10-24 Akim Demaille <akim@epita.fr>
10443 * lib/Autom4te/General.pm (backname): New.
10445 2001-10-24 Akim Demaille <akim@epita.fr>
10447 * m4/: Remove, merged into...
10448 * config/: here.
10450 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10452 * doc/autoconf.texi (Shellology): Mention the problems with bash
10453 2.05's use of ANSI quoting in its `set' builtin.
10455 2001-10-22 Paul Eggert <eggert@twinsun.com>
10457 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10458 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10459 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10460 POSIX decided to standardize on the int flavor of strerror_r.
10461 Always do char* test, as there's no reason not to.
10462 Assign to a char* var, to catch strerror_r that returns int*.
10464 * doc/autoconf.texi (Particular Functions):
10465 Document the above changes. Also, document the fact that
10466 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10468 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10470 2001-10-20 Akim Demaille <akim@epita.fr>
10472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10473 the executable was missing from the log.

10477 * lib/Autom4te/General.pm (&update_file): If destination is
10478 unchanged, remove the source.
10479 (&up_to_date_p): Don't be verbose, be debug.
10480 * bin/autoreconf.in: No longer support --m4dir.
10481 (&autoreconf): Display the full path of the configure.ac we are
10482 studying.
10483 Trace it only once.
10484 Be sure to honor --force with gettextize.
10485 Always run aclocal.
10486 * doc/autoconf.texi: Adjust.
10488 2001-10-20 Akim Demaille <akim@epita.fr>
10490 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10491 Remove, dead.
10492 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10493 `intl' is already present, as it refuses unless --force.
10494 (&parse_args): Use -I, --include instead of the old Autoconf
10495 options.
10496 ($localdir, $autoconf_dir): Remove.
10497 (@include): New.
10498 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10500 2001-10-19 Jens Petersen <petersen@redhat.com>

10508 file in @configure_input@.
10509 Don't mention `automatically' in addition to `generated'.
10510 * tests/torture.at (#define header templates): Adjust.
10512 2001-10-19 Akim Demaille <akim@epita.fr>
10514 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10515 comment, explain how to install automatic mode selection.
10516 From Russ Allbery.
10518 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10520 * bin/autoreconf.in (autoreconf): Display the path to the
10521 configure.ac being studied.
10523 2001-10-18 Paul Eggert <eggert@twinsun.com>
10525 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10526 long, to work around a bug in the HP C compiler version HP92453-01
10527 B.11.11.23709.GP.
10529 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10530 (AS_BASENAME_EXPR): New macro.
10531 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10532 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10533 and fall back on 'sed' only if the other two fail. This makes
10534 AS_BASENAME act more like AS_DIRNAME.
10535 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10536 contains white space.
10537 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10538 Use AS_DIRNAME, since I think it's now DOS-friendly.
10539 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10540 Allow "dirname //FOO" to return either / or //, as POSIX allows
10541 either behavior.
10543 2001-10-10 Akim Demaille <akim@epita.fr>
10545 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10547 From Eric Sharkey.

10551 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10646 2001-10-08 Akim Demaille <akim@epita.fr>
10648 Use `add-log-current-defun-function' for ChangeLog creation.
10649 Suggested by Tom Tromey.

10680 shell does not support LINENO, and if CONFIG_SHELL is unset or
10681 empty, and if we can find a shell that does support LINENO,
10682 then set CONFIG_SHELL to that shell and then re-execute
10683 ourselves with CONFIG_SHELL.
10685 2001-10-05 Paul Eggert <eggert@twinsun.com>
10687 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10688 doesn't exist. Remove *.tmp, as a .tmp file is created during the
10689 build of $(TESTSUITE).
10691 2001-10-05 Akim Demaille <akim@epita.fr>
10693 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

10714 (AS_SHELL_SANITIZE): here. Use it.
10715 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
10716 From Paul Eggert.
10718 2001-10-04 Akim Demaille <akim@epita.fr>
10720 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
10721 combination of Awk and sed to replace $LINENO.
10723 2001-10-02 Paul Eggert <eggert@twinsun.com>
10725 * doc/autoconf.texi (Limitations of Builtins): You can't use
10726 "source"; it's not portable. Remove confusing and
10727 somewhat-incorrect example involving "." and "/".
10729 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
10730 compatibility with POSIX shells.
10732 2001-10-02 Akim Demaille <akim@epita.fr>

10735 instead of exec'ing to preserve $0 and $@.
10737 2001-10-01 Akim Demaille <akim@epita.fr>
10739 * tests/testsuite (AT_INIT) <at_pass_list>: New.

10758 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10759 Don't use nested parenthesization. This patch was originally
10760 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10761 but somehow it didn't get incorporated then.
10762 * doc/autoconf.texi (Limitations of Usual Tools):
10763 Clarify remark about sed and nested parenthesization.
10765 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
10766 Report an error if the size cannot be determined even though
10767 the type exists.
10768 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10769 Check for `expr' arithmetic overflow, and for compilation failure,
10770 and invoke a new argument $4 if either is discovered.
10771 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10772 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10774 2001-09-28 Akim Demaille <akim@epita.fr>

10782 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
10783 (AT_TESTED): this.

10788 2001-09-27 Akim Demaille <akim@epita.fr>
10790 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10791 generates too many bug reports.
10793 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10794 status when executing the ACTION-IF-FALSE.

10803 (Broken/missing compilers, AC_PROG_CPP with warnings)
10804 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10805 (AC_PROG_CPP requires AC_PROG_CC): here and...
10806 * tests/fortran.at (GNU Fortran 77): there.
10807 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10808 AC_TRY_RUN is about compilation, not shell commands.
10809 (Test Programs): AC_TRY_RUN works as used to be advertised.
10811 2001-09-27 Akim Demaille <akim@epita.fr>
10813 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10814 Raja R Harinath:
10815 Be sure to detect when $LINENO always returns the same value.
10816 Look for the original script, basename($0) is certainly not
10817 enough.
10818 Pass the CLI arguments to `$as_me.lineno'.
10820 2001-09-25 Akim Demaille <akim@epita.fr>

10830 of --language now.
10832 2001-09-23 Akim Demaille <akim@epita.fr>
10834 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10836 2001-09-23 Akim Demaille <akim@epita.fr>
10838 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10839 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10840 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10841 builddir, buildpath, top_builddir, and top_buildpath.
10842 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10843 the current directory.
10844 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10845 variables *before* changing the current directory.

10848 variables.
10850 * lib/autotest/general.m4: Do not reset AT_victims.
10851 Don't compute at_srcdir nor at_top_srcdir.
10853 * tests/tools.at: Hence use top_srcdir.
10855 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10856 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10857 Remove.
10858 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
10859 * tests/wrapsh.in, tests/autoupdate.in: New.
10860 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10861 * configure.ac: Build the position independent wrappers.
10863 * man/Makefile.am: Now that test wrappers are position
10864 independent, use them and drop dark envvar magic.
10866 2001-09-23 Akim Demaille <akim@epita.fr>
10868 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10869 (Programming in M4sh): this.

10887 over-escaping.

10897 (Autoconf): Adjust.
10899 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
10901 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

10908 for $LINENO.
10910 2001-09-22 Akim Demaille <akim@epita.fr>
10912 * lib/autoconf/autotest.m4: Create `package.m4'.
10913 * tests/Makefile.am (package.m4): Remove.
10915 2001-09-22 Akim Demaille <akim@epita.fr>
10917 Rely on `$LINENO' when possible instead of `__oline__'.
10919 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10920 `$LINENO' support replacement when not supported.
10921 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10922 them explicitly to be sure they are not output before this section
10923 (via m4_require). Cosmetic only.
10924 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10925 * lib/autoconf/programs.m4: Replace all the occurrences of
10926 `__oline__' with `$LINENO'.

10929 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10931 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10932 character (u: -> ue) in a code comment.
10933 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10934 it works.
10936 2001-09-21 Akim Demaille <akim@epita.fr>
10938 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10939 Suggested by Jim Meyering.
10941 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10943 * lib/autoconf/programs.m4: Use extensions listed in
10944 $ac_executable_extensions when looking for programs.
10946 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10948 * lib/autoconf/general.m4: Fix a small Englisho.
10949 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10950 setting up ac_dir_suffix and ac_top_builddir.
10951 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10953 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10955 * doc/autoconf.texi (File System Conventions): Clarify the use of
10956 PATH_SEPARATOR.
10957 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10958 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10959 be used instead of ':'.
10960 * lib/autotest/general.m4: Replace occurrences of ':' in
10961 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10963 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10965 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10966 arguments. Fixed a typo.
10968 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10970 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10971 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10973 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10975 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10976 * bin/autoupdate.in: Ditto.
10977 * bin/autoheader.in: Reworded a few comments.
10978 * bin/autoconf.in: Reworded help text for a few options.
10979 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10980 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10982 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10984 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10985 already have $file). Set output files to binary mode (helps avoid
10986 CR issues on DOSish systems).
10988 2001-09-19 Akim Demaille <akim@epita.fr>
10990 * lib/autotest/general.m4: Englishoes.
10991 From Tim Van Holder and Alexey Mahotkin.
10993 2001-09-18 Paul Eggert <eggert@twinsun.com>
10995 * doc/autoconf.texi (Common Shell Constructs): New node,
10996 documenting AS_DIRNAME.
10997 (Limitations of Usual Tools): Refer to it when discussing dirname.
10998 Also, update discussion of POSIX standard to reflect latest draft.
11000 * lib/autoconf/c.m4:
11001 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
11003 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
11004 Do not pass a first argument with leading '-'
11005 to expr, by parenthesizing initial integers that might be negative.
11007 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
11008 now merely checks whether it is an error to pass an argument
11009 to getpgrp.
11011 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11012 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11013 whether it is a (compile-time) error to pass an argument to
11014 getpgrp. This simpler test supports the revised documentation,
11015 and is all that AC_FUNC_GETPGRP's users really need.
11017 2001-09-18 Akim Demaille <akim@epita.fr>
11019 * doc/autoconf.texi (Limitations of Make) <$<>: New.
11021 2001-09-18 Akim Demaille <akim@epita.fr>
11023 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
11024 `{}'.
11025 * lib/autotest/general.m4 (AT_INIT): Adjust.
11027 2001-09-18 Paul Wagland <paul@wagland.net>
11029 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
11030 correctly.
11031 Add test for AS_BASENAME.
11032 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11033 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11034 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11035 * tests/base.at: Fixed the expected responses. The old ones were
11036 one line out...
11037 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11038 the documentation claims it should (and how it behaved in 2.13).
11040 2001-09-18 Akim Demaille <akim@epita.fr>
11042 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
11043 the AC_CONFIG_COMMANDS invocation.
11044 This also solves the name clash problems.
11045 Don't set the package's ID.
11046 * lib/m4sugar/Makefile.am (version.m4): Revamp.
11047 No longer to be shipped.
11048 (version.in): Remove.
11049 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
11050 * lib/autoconf/status.m4: Adjust.
11051 Use `m4_PACKAGE_STRING'.
11052 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11053 the only optional argument is the name of the test suite.
11054 Expect `package.m4' to define the package signature.
11055 * lib/autom4te.in (Autotest): Add `package.m4?'.
11056 * tests/Makefile.am (package.m4): New.
11057 * tests/suite.at: ifnames is a victim.
11059 2001-09-18 Akim Demaille <akim@epita.fr>
11061 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11062 AC_LIBSOURCE, AC_CONFIG_FILES.
11063 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11064 program version string doesn't match the package's.
11065 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11066 after `(cached)'.
11068 2001-09-17 Paul Eggert <eggert@twinsun.com>
11070 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11071 Allow expression to return any value that can fit into unsigned long
11072 (not int, as before). Check for output errors.
11074 2001-09-17 Bruno Haible <haible@ilog.fr>
11076 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11077 Always include <stdio.h> and <stdlib.h>. Evaluate
11078 the expression in an extra function before these includes. Call
11079 fprintf "%d" only after ensuring the argument is of type 'int'.
11080 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11082 2001-09-17 Paul Eggert <eggert@twinsun.com>
11084 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11085 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11086 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11087 when they don't exist.
11089 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11090 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11091 need it.
11093 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11094 version with the version used by fileutils 4.1, except use
11095 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11096 we don't need it.
11098 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11100 2001-09-13 Akim Demaille <akim@epita.fr>
11102 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11103 _first_.
11104 Reported by Gerrit P. Haase.
11106 2001-09-13 Akim Demaille <akim@epita.fr>
11108 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
11109 m4_defn'ing is valid.
11111 2001-09-13 Akim Demaille <akim@epita.fr>
11113 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
11114 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
11115 Use it.
11117 2001-09-13 Akim Demaille <akim@epita.fr>
11119 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
11120 m4_match.
11121 (m4_re_escape): New.

11252 2001-09-05 Akim Demaille <akim@epita.fr>
11254 Be ready to handle filenames as stupid as `dnl.at', for if even
11255 the maintainer is dumb enough to do that...
11257 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11258 excellence in M4 quotation: consider `__file__' is active.
11260 And BTW, when invoking m4, pass the --include in the right order:
11261 the wrong one.
11263 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11264 4m.

11291 New, extracted from main.
11292 Use IO::File wherever possible.
11293 (input.m4): Be constant, use -I instead of hard coding $tmp.
11294 Therefore be a quoted heredoc.
11295 Don't invoke `_au_disable', since ac was not loaded, but just
11296 `unm4.m4'.
11298 2001-08-31 Akim Demaille <akim@epita.fr>
11300 Version 2.52d.

11325 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11326 (testsuite Scripts): There is no such thing as `atconfig.in'.
11327 And actually one diagram is missing: test suite runtime.
11329 2001-08-31 Akim Demaille <akim@epita.fr>
11331 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11332 inverse order.
11334 2001-08-31 Akim Demaille <akim@epita.fr>
11336 * bin/autoupdate.in (@include): `installcheck' revealed the path
11337 to m4sugar was lacking!
11339 2001-08-31 Akim Demaille <akim@epita.fr>
11341 * man/Makefile.am (.x.1): We really have to pass
11342 autom4te_perllibdir.
11344 2001-08-31 Akim Demaille <akim@epita.fr>
11346 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

11352 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11353 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11354 Use directly autom4te, not autoconf.

11379 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11380 (autoheader): Pass --force since the test suite goes too fast for
11381 the time stamps.
11382 Adjust to the new autoheader messages.
11384 2001-08-31 Akim Demaille <akim@epita.fr>
11386 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11387 Check the completeness of the #template.

11397 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11398 `autoheader: `config.hin' is created'.
11399 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11401 2001-08-31 Akim Demaille <akim@epita.fr>
11403 * bin/autoheader.in: Rewrite in Perl.

11406 2001-08-31 Akim Demaille <akim@epita.fr>
11408 * bin/autoconf.in (--include, -I): New option.
11409 Map --localdir, --autoconf-dir onto it.
11410 Forward autom4te's options instead of interpreting them.
11411 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11412 There is no such envvar since the inception of autom4te.cfg.
11413 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11414 * bin/autoupdate.in: Adjust, and perform more control.

11418 2001-08-31 Akim Demaille <akim@epita.fr>
11420 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11421 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11422 optionally `FILE'.
11423 Use -e, not -f, since /dev/null for instance is OK.
11424 (&parse_args): Adjust.
11425 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11427 2001-08-31 Akim Demaille <akim@epita.fr>
11429 * configure.ac: Also find tested executables in bin.
11430 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11431 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11432 installed peer executables, only PATH is allowed to resolve it.
11433 Pass `autoconf_dir' via options, not via invisible envvars.
11434 * lib/Autom4te/General.pm (&find_peer): Remove.
11435 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11436 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11437 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11438 find the executables for it.
11439 * tests/Makefile.am: Major cleanup. Too lazy to document...
11440 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11441 We only need PERL.
11442 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11443 indeed related to running the test suite, while passing
11444 --autoconf-dir and others is related to running non installed
11445 Autoconf executables. So don't do that, leave it to...
11446 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11447 * tests/autoscan: New.
11448 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11449 refer to library files: rely on --language.

11453 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11462 2001-08-29 Akim Demaille <akim@epita.fr>
11464 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11465 Suggested by Paul Eggert.
11467 2001-08-29 Akim Demaille <akim@epita.fr>
11469 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11470 download in a tmp dir.
11472 2001-08-29 Akim Demaille <akim@epita.fr>
11474 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11493 * lib/autotest/general.m4: Use
11494 foo=`(command) 2>/dev/null`

11497 (at-devnull): Rename as...

11499 (--clean): Remove AT-* files too.

11535 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11536 Support `VAR=VAL' as arguments.

11556 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11557 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11558 readable.
11559 Adjust callers.
11560 * doc/autoconf.texi (Configuration Actions): Document the vars
11561 available in commands.
11562 Emphasize the risks of collisions in init-cmds.

12018 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12020 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12021 magic values from an object file when cross-compiling.
12022 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12024 2001-08-10 Akim Demaille <akim@epita.fr>
12026 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12027 effects.
12028 Suggested by Russ Allbery.
12030 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12032 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12033 current $prefix to the sub-configures.
12035 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12037 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12038 extension (needed on BeOS). Reported by Guido van Rossum.
12040 2001-08-09 Akim Demaille <akim@epita.fr>
12042 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12044 2001-08-07 Akim Demaille <akim@epita.fr>
12046 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12047 removed.
12048 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12049 No need to remove the files before and after the each test, before
12050 each test and at the end of the suite is enough.
12051 Display only the children `times', not the shell's.
12052 If the test failed or was skipped, at-times is not available.
12054 2001-08-07 Akim Demaille <akim@epita.fr>
12056 Always produce testsuite.log, including when there are no
12057 failures. This helps getting information on skipped tests, and
12058 duration of the tests. Err, implement the latter btw.
12060 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12061 Dump information on the first run of each test.
12062 (AT_CLEANUP): Create `at-times' containing the duration of the
12063 test group.
12065 2001-08-07 Akim Demaille <akim@epita.fr>
12067 The use of `dumpstat' revealed that `len' was used although it
12068 should not. m4_text_wrap was using it, but in the Autoconf world
12069 where it is legal. Hence (i) test M4sh in its own world, not
12070 Autoconf's, and (ii), ahem, fix the bug :)
12072 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12073 does not like `' instead of [].
12074 (AT_INIT): Forbid `^_?AT_'.
12075 And don't output such tokens.
12076 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12077 `script.as', and `autom4te.cache'.
12078 Remove `empty' and `macro' which are no longer used.
12079 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12080 * tests/m4sugar.at: Use it.
12081 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12083 2001-08-07 Akim Demaille <akim@epita.fr>
12085 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12087 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12089 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12091 2001-08-04 Akim Demaille <akim@epita.fr>
12093 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12094 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12095 AC_TRY_LINK.
12096 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12097 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12098 (AC_F77_MAIN): Likewise.
12100 2001-08-04 Akim Demaille <akim@epita.fr>
12102 Don't rely on M4sugar outputting the patterns in files, since we
12103 might process the output _without_ running m4, hence without these
12104 files.
12106 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12107 * bin/autom4te.in (@Request::includes): Remove, unused.
12108 (@Request::source): Rename as...
12109 (@Request::input): this.
12110 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12111 (&handle_output): Fetch the patterns from the traces.
12112 `$forbidden' and `$allowed' are constant: use m//o.
12113 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12114 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12116 2001-08-04 Akim Demaille <akim@epita.fr>
12118 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12119 autoconf', i.e., in addition to caching traces, cache the output.
12121 * bin/autom4te.in (Request::cache): Rename as...
12122 (Request::id): this.
12123 ($cache, $icache, $tcache, $ocache): New.
12124 (&handle_m4): Save M4 output in the cache instead of $tmp.
12125 (&handle_output): Adjust.
12126 (&up_to_date_p): Check that the output cache is up to date too.
12127 (top level): Run `&handle_m4' iff force or the cache is invalid.
12128 Run `&handle_output' if the output cache is more recent.
12130 2001-08-04 Akim Demaille <akim@epita.fr>
12132 * bin/autom4te.in ($force): New.
12133 (&parse_args, &print_usage): -f, --force is a new option.
12134 (&handle_output): CPP directives might have spaces after `#'.
12135 (&parse_args): The first file only can be frozen.
12137 2001-08-04 Akim Demaille <akim@epita.fr>
12139 Don't let autom4te compute the `include' traces several times:
12140 first check that the trace cache file is up to date, and then
12141 compare its timestamp with that of the output.
12143 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12144 the preamble. Don't require 5.005 as Autom4te::General does it,
12145 and better yet (use `use', not `require'!).
12146 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12147 Class::Struct as Autom4te::Struct.
12148 * lib/Autom4te/General.pm (File::stat): Use it.
12149 (&mtime): New, export it.
12150 * bin/autom4te.in: Use it.
12151 Declare `$req' is invalid if it is outdated.
12152 Don't declare it valid before saving it if something went wrong.
12154 2001-08-04 Akim Demaille <akim@epita.fr>
12156 Autom4te shall not encode Autoconf data, and preselecting traces
12157 must be proposed to the users.
12159 * bin/autom4te.in (@required_trace): Remove.
12160 (@preselect): New.
12161 (&parse_args, &print_usage): -p, --preselect is a new option.
12162 (&up_to_date_p): Adjust.
12163 * bin/autoconf.in: Preselect some Autoconf macros.
12165 2001-08-04 Akim Demaille <akim@epita.fr>
12167 * tests/tools.at (autoconf --trace: user macros): Check traces on
12168 macros invoked without arguments, and macros invoked with multiple
12169 lines arguments.
12171 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12173 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12174 arguments.
12176 2001-08-03 Akim Demaille <akim@epita.fr>
12178 * bin/autoconf.in ($@): Work around the usual sh bug.
12179 From Nicolas Joly.
12181 2001-08-03 Akim Demaille <akim@epita.fr>
12183 Clean up the handling of the M4 builtins tracing exception.
12185 * bin/autom4te.in (Request::request): Don't complete M4 builtins
12186 trace requests.
12187 (@m4_builtins): Rename as...
12188 (@m4_builtin): this.
12189 (%m4_builtin_alternate_name): New.
12190 (&parse_args): Complete the trace requests with alternate names.
12191 (&handle_traces): Hence no longer do it here.
12192 (&trace_requests): Remove, unused.

12196 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
12197 m4_if, and m4_wrap.

12201 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
12202 (m4_divert_pop): Dump the whole diversion stack when a diversion
12203 mismatch happens.
12204 * bin/autom4te.in (&handle_output): Remember of the first
12205 occurrence of a possibly undefined macro, not the last.
12206 Complain about the possibly undefined macros in the same order as
12207 the appear in the output.
12208 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12209 * tests/tools.at (autoconf: forbidden tokens, basic)

12211 autoconf's stderr, as it is now deterministic.
12212 Check that `dnl' is caught.
12214 2001-08-01 Akim Demaille <akim@epita.fr>
12216 * configure.ac: Bump to 2.52c.

12671 cross-language link tests can be performed successfully.
12672 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12673 after $LIBS, for consistency; this should be the general rule since
